If any of your extensions stop working, install the Nightly Tester Tools extension and choose "Override Compatibility" for those. Voila.

Rae

Kemp Temp doesn't work either :S

LifesSweetDrug

My Tab Mix Plus no longer works.

Ruiz

tab mix plus, wootwatcher, and dragdropupload all broke for me with this update...

milrtime83

I have not installed this update yet, as it says it will cause TwitterFox to stop working. I'll wait a day or so to see if the add-on gets an update, then I'll update FF as well.

ladypoetess

Remember the Milk for Gmail was identified as incompatible.

rraheja

Autocopy was disabled with the update. Everything else was ok.

Letsgohokies

This update won't cause any add-on incompatibilities.

Two of mine aren't working now. Not that big of a deal though.

Famf

For some reason, adding bookmarks became a lot harder with FireFox 3.0, does this fix it?

NumberFiveIsAlive

This update won't cause any add-on incompatibilities.
Not true in my case as it complained about Abduction and Tab Mix Plus which I had working under 3.0. Firefox has now disabled those add-ons for me. Maybe I can make a few tweaks in the install.rdf files to get them back.

vanjos72

now half my add-ons dont work, including my most important one! i thought there werent supposed to be any add-on incompatibilities caused by it!!!

shukcb04

Thanks for the info.

Calvin Blackburn

tnx for letting me know!

soulslave

@ヨシダさん 25
I hope so! That is a very annoying issue!

Gears is marked as not compatible for me.

Kraft

Will this fix the issue of all new windows starting in small-ass minimized size?

ヨシダさん 25

@DWHarrison: works for me

ghostwind

Thank you, Rae. That worked for me on Tab Mix Plus and it took about 30 seconds.

caprice

Seems like scrolling with static backgrounds is a little better. Not perfect, but better.

PatrickTulskie

It says Google Gears won't work when I go to check for updates. I'd rather just keep Firefox open for now, as apparently the attack can only run when the 'fox is closed and another internet-enabled application is running, according to Mozilla.

geekblake

Does it fix the URL bar? If not, I'm not interested.

urukhaifive

Did they fix the cookie issue yet?

OX4

@NumberFiveIsAlive: just click the star in the address bar, or drag the iconm on the left of the address bar into your bookmarks. Seems easy to me!

patrickjdub2

iFox 3 doesn't work. i guess i can put up with the default browser theme for a few days...

weatherking

Sadly, the upgrade screen says Better GCal does not work in 3.01.

DWHarrison

all of my add-ons still work, it put me back on the page i was on and it fixed my overbite. i have nothing to complain about and the world's still turning...

0zSpitt

Does anyone know if this update fixes the Vista incompatabilities? Firefox 3 worked fine on my Win XP machine but my two Vista machines did not like it at all. Tons of crashes.

tcatnat

Tab Mix Plus is really useful to me, and so I'm going to defer upgrading for as long as possible. Hopefully, TMP will get an update soon, but I won't be holding my breath.

aj_robins

Oh, and to download 2.0.0.16:

Go to [www.mozilla.com] .

You will see a long list of localized versions of (at this writing) 2.0.0.16 with columns for Windows, OS X, and Linux. Take your pick of language and OS.

nightbirdsf

ifox graphite and bookmark sorting extensions no longer work.

Still missing my Google maps extension from 2.x as well. Sidebar variant no where near as good.

marcmarc

@nightbirdsf:
i'm in the same boat... for me, ff will freeze up while I'm typing and stop taking input, as well as just randomly go back while the focus is stolen from my typing task. If it's not solved soon, FF3 is going to be history on my system.

gankit

I don't use many add-ons. But on Vista, about 2 minutes after starting Firefox, my browser freezes for maybe 5 minutes then continues again like nothing happened. Also, there is a long delay before Live Bookmarks RSS is updated.

I'm at the point where I'm going to burn Firefox 3.0 to the ground and install 2.0.0.16.

nightbirdsf

i wish i didn't install this because tab mix plus won't work anymore. anyway of turning back time on this one?

jemstarr

Evernote web clipper does not work.

njbrett

The following add-ons not working:

Google Gears 0.3.24.0

MacOSX Theme 0.5.8

TabMixPlus 0.3.6.1.080416

apex2000

Just seconding above comments that Tab Mix Plus and dragdropupload no longer work, argh.

julieulie

@DWHarrison: Better GCal 0.3 is working here.

All: Just updated the post. I had no add-on compatibility issues myself, and the Firefox folks said that unless the manufacturer didn't list their extension as compatible with 3.0.* like you were supposed to, there would be no problems.

Gina Trapani

boo, ditto on the add-ons.

also what "close" button is the FF welcome page talking about?

kirksucks

Only I having system slow down and processor hog when some Flash embedded sites are open? (Like some youtube videos, and some sites with Flash Banners)???
It happens to me since version 2.x...

Tiago Loges.

tloges

pull the article!

Lil-ndn

Restart Firefox and Download manager tweak don't work now either.

Please, do your homework next time LH!

johnhorneguitar

Oh my god, all my add-ons reset to its first-time run, all the settings lost !

icyrainz

AGH! I should have read the comments. I installed it, but then Tab Mix Plus went out - a rather important add-on for me. Why the heck don't they display this in the BEGINNING of the install?! I would have chosen NOT to install it and waited until that issue was resolved.

Any how, I had to go on a hunt for the old version (downloaded it off of some site and am hoping that it didn't install anything else). AGH!

T.

pojken

finally! I was getting 1-12 random crashes a DAY!

dalekg

By the way here is how to get Tab-Mix Plus working if you want:

Grab the dev version from here, SAVE it to your desktop, don't "install" it.

[tmp.garyr.net]

Then:

COPIED FROM [tmp.garyr.net]
**************
Right-click on it.
Select 'open with' if available, otherwise, select 'open'.
Choose 'select the program from a list'.
In subsequent dialogue box, select WinRar (7Zip worked for me.)
At the top level of the archive you should find 'install.rdf'.
Drag 'install.rdf' to the desktop.
Right-click on it.
Select 'open with' if available, otherwise, select 'open'.
Choose 'select the program from a list'.
In the subsequent dialogue box, select Notepad (GVim worked for me.)
Search for line 'em:maxVersion="3.0"'.
Replace "3.0" with higher version. ("4.0" worked for me.)
Save file.
Drag 'install.rdf' from desktop back into the archive, overwriting existing file.
Exit Notepad, WinRar and delete install.rdf from your desktop.
Drag the .xpi from your desktop into your FF window. Install.
Delete the .xpi from your desktop (or save it, your choice.)
***********

I actually changed it to 3.0.1 (it was "3.0"), and used WinRar, and it all worked fine.

jsmorley

@cipotefello:

Oh, I see what you are getting. It says that IF you have the update page that you are sent to after it installs still loaded in a tab.

jsmorley

@cipotefello: Nevermind

cipotefello

@cipotefello:

Really? Mine says "Firefox 3.0.1 More Secure and Stable - Mozilla Firefox"

jsmorley

For some reason this update makes firefox say Update------ in the window title, kinda annoying

cipotefello

I had no problem with any addons EXCEPT the "dev version 0.3.6.1.080416" of Tab-Mix Plus. It went dark. I am about to give up on Tab-Mix Plus anyway, as it has been in this semi-broken state for months. So all in all I didn't have any real problem.

I run

Adblock Plus
Customize Google
Download StatusBar
GMail Notifier
McAffee Site Advisor
Pronounce
Quick Drag
Speed Dial
StumbleUpon
GooglePedia

jsmorley

Thanks LifeHacker, I would not have known about it if I didn't see it here. All my add-ons still work. Hopefully it will stop FF3 from dropping my cookies every 5 minutes.

scerwup

Does anyone NOT use Tab Mix Plus? It's pulling teeth without it.

nerdly

Only had TMP and Adobe DLM fail as incompatible, everything else still up. Lately, been having an issue where FF3 will crash everytime I try to load a pdf. I've reinstalled all my Adobe software and it still happens; maybe this fixes it??

Petah

Since it's a bugfix update, I doubt it actually causes compatibility problems. It's probably just that the plugin author specified 3.0 exactly as the max version, instead of 3.0.*.

For those of you having problems with Firefox reporting extension incompatibility:

You can just set bool extensions.checkCompatibility in about:config to FALSE to stop it doing that... I'd probably advise turning it back on after all your extensions fix that, to stop you from installing something that IS incompatible. Or you could go and edit the install.rdf of all the problematic extensions.

Laogeodritt

evreything is working fine for me - even google gears...
i was suprised because i run vista, and that's where all the bugs usually are...

Charging_Mooses

No problemo! No broken add-ons, no broken themes, nada!

Have a nice day.

LittleEnosBurdette

@pojken:

I did post a way to get Tab Mix Plus working if you want. Just look up 3 posts.

jsmorley

Everytime I close the "http://kirainet.com/english/" in a tab or window FF3 closes entirely. This update didn't fix it.

CutePuppyz

hyperwords incompatible too.

nafnosseb

I can't change themes now; I'm stuck with the default theme. Way to go, Mozilla.

WasatchMan

@tcatnat:

i have Vista Home Premium with or without SP1 Firefox 3 works like a charm. as i have mentioned in Firefox forums, this kind of problems as well as Full Hotmail problems are not with Firefox 3 or caused by Firefox 3. it is caused by individual user's PC configuration. we all know installing and uninstalling stuff in Windows causes instability with it.

JadeEmperor

eMusic Remote Helper and DragDrop Upload aren't working for me on my Mac (although I don't suppose this will be any different on my PC),

crichton007

@Petah: install Foxit Reader and uninstall adobe reader. much easier and faster.

patrickjdub2

Use MR tech to make incompatible add ons compatible.
Just right click and select make compatible after the install.
[www.download.com]

patrickjdub2

crap now the bootleg Fasterfox plugin that i got from the review section of the atcual outdated plugin, not working...

hopefully someone will bootleg is again and up it in the review comments =)

these don't work for me now :

Fasterfox 3.0.0
Adobe DLM 1.5.2.19
Tab Mix Plus 0.3.6.1.080416

Energeegod

just restarted and all my addons work. nice :-)

but lh threaded is not working(?) it seems.

JadeEmperor

Sweet, hopefully this fixes the issues with FF3 crashing randomly on my Mac. Going on about 15 minutes now without any crashes, which is about 10 minutes longer than I was getting previously on average (sometimes it would even crash after literally one second... crash, relaunch, immediate crash). I was starting to get extension withdrawal from switching back to plain-jane Safari.

okmnji

I'm using the iFox Smooth theme so will hold-fire until that get's an update.

The plus side though is that reading the comments here shows me add-ons that others are using that sound really useful!

PatrickRS

all my addons work after FF 3.1 install. thanks jsmorley

I even made MinimizeToTray work

reedjaguar

W@cipotefello: Yeah.
It says in the titlebar "Firefox: Firefox 3.0.1 More Secure and Stable - Mozilla Firefox". But it isnt this Version that you have, it is the avaible update. I have Firefox/3.0 installed. weird.

MrKlappstuhl

:( Better Lifehacker extension no longer works right, I lost my nested comments.

scerwup

are the flash player issues fixed? firefox 3 combined with flash player 10 or in some cases 9, caused strange bugs with interaction in flash movies.

little computer freund

@MrKlappstuhl: I had a momentary freak out about that too... but it's the name of this article!!

JuniorBruce

Piclens stopped working :|

soulcabbage

In addition to my post at 04:13

The Orbit downloader add on is also working again thanks to Rae.

ez13

Thanks for the headsup on this update, i just downloaded & installed it and everything seems to be working as usual with all my add-ons working fine.

stonebridge

how do I get the update for ubuntu ?

ThePrisoner

@Rae: thx man, you made my day, got tabmixplus back in business!

But, the Gawker Comments HTML Helper has died in the process?

ez13

I dunno perhaps using Lifehacker is causing a dimunition of brain cells. The update service (Help>Check for Updates) specifically says:
"This update will cause some of your extensions and/or themes to stop working until they are updated"
Pressing "Show List" even lists the ones that won't work! Given the invaluable TabMixPlus is there and there seems to be a glitch with the TMP makers getting out a final version - I'm going to pass on this update for now.
Also FF3 politely informs me of its updates with a little slide in notice - has no-one seen this?

idodialog

@4:13
The Gawker Comments HTML Helper is NOT dead, at least not after updating (sorry Gina).

ez13

@MrKlappstuhl:
It says that, because you are viewing Lifehacker Page with that topic 'Firefox 3.0.1 More Secure and Stable" :)

Go to a different page and you will see it says something else.

DasLife

After struggling for more than a week with FF3 with multiple crashes and Gmail hanging every 15 minutes, I finally threw in the towel and went back to FF2. My experience may be somewhat unique I'm not sure...but in my opinion, the FF3 launch was a disaster.

willisja

Hey guys, I have seen so many different posts on tweaks to get addons to work. Why not just use Mr. Tech local install? It is available from mozilla addons:

[addons.mozilla.org]

DasLife

Just lost UnPlug. Not a huge loss, though. Never had Tab-Mix-Plus...but now I'm curious. Figures.

edicius

@DasLife: @JuniorBruce:
Definatly LOL! :D

But as long as TabmixPlus isnt working i will not install that update.

MrKlappstuhl

the problem with firefox is all this add-on bullshit. mozilla have to keep patching and fixing and plugging holes, resulting in tons of broken plugins. so you wait as on by one the plugins get updated, only for mozilla to move the goal again. ff should have the top plugins as PART OF FIREFOX. dont ask "which ones are top???" because its FREAKING OBVIOUS

Tactical-Incineration-Development

It's up to you guys of course, but I would consider if you really want to run about:config and disable the version checking or run MR Tech.

The problem with this is that you can later forget you did, and easily install an addon that really IS incompatible, making a mess of things.

Take a look at my earlier post (and the one right above this, for a way to force individual addons to appear to be the correct version. Do this and you can get that addon with just the incorrect version number (like Tab Mix Plus) to work, without removing all version protection.

jsmorley

I noticed that Foxmarks works for me now, which I'm happy for because that's my most important little add-on.

chareverie

Same Workaround with other Tools:

[addons.mozilla.org]
[tmp.garyr.net]

------------------------------------------------------
Save .xpi to desktop.
Right-click on it.
Select 'open with' if available, otherwise, select 'open'.
Choose 'select the program from a list'.
In subsequent dialogue box, select WinRar (7Zip worked for me.)
At the top level of the archive you should find 'install.rdf'.
Drag 'install.rdf' to the desktop.
Right-click on it.
Select 'open with' if available, otherwise, select 'open'.
Choose 'select the program from a list'.
In the subsequent dialogue box, select Notepad (GVim worked for me.)
Search for line 'em:maxVersion="3.0"'.
Replace "3.0" with higher version. ("4.0" worked for me.)
Save file.
Drag 'install.rdf' from desktop back into the archive, overwriting existing file.
Exit Notepad, WinRar and delete install.rdf from your desktop.
Drag the .xpi from your desktop into your FF window. Install.
Delete the .xpi from your desktop (or save it, your choice.)
------------------------------------------------------

works fine.

MrKlappstuhl

If you guys are having compatibility issues, just grab the Nightly Tester Tools extension here:

[addons.mozilla.org]

With that you can override Firefox's compatibility checking.

Though, I still have one remaining gripe with Firefox 3. It doesn't remember my open tabs when I close it using the 'x' in the upper-right.

But if I close it by selecting 'File\Exit' it will.

I've seen the bug report on Mozilla but can't find it right now (too early).

Has anyone else experienced this? Anyone know of a fix?

sanks

It's to the point where I'm about to throw in the towel with Firefox. I LOVE Firefox. But, my goodness. I am sick of it crashing every ten minutes. I've disabled all my add-ons, but it seems it hates every single add-on to do with Gmail, even Better Gmail. Anyone else having problems?

It hasn't crashed today, not for a whole hour, so maybe that's good sign. I would like my add-ons back!

spyscribbler

Mr. Tech does a LOT of things that users may find handy.... look at the reviews on Mozilla addon page. One can toggle compatibility checker easily.

DasLife

@vanjos72: also busted autocopy for me, nightly tester fixed it.

caedus

I'm running Vista SP1 and the update along with all my extensions seem to be working fine. I don't use TMP since I only needed a couple features that other extensions provide. Regardless, TMP users should edit about:config or install MR Tech and call it a day.

jonny6pak

wtf... all my bookmarks are gone now, and the home page does not want to stick... it always starts on a blank page.

mpeluffo

phew, i uninstalled and reinstalled and bookmarks are back, everything works

mpeluffo

Awesome! Firefox finally stops crashing!

skylive

All my add-ons work fine, and so does TUAW.com

bunny182

Looks like I can add GoogleGears to the list here at work as well as TabMixPlus both here and at home.

Interesting that different people are suffering different fails.

parkylondon

@suburbancowboy:

My suggestion would be:

Go to the folder: C:\Users\yourname\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxx.default

copy the bookmarks.htm file found there.

Now uninstall Firefox and reinstall the 3.0.1 version

Import your bookmarks from the bookmarks.htm file you saved

Go to [addons.mozilla.org] and install the addons you like to use one at a time and be sure Firefox is happy between each install.

This should correct any problems.

jsmorley

TwitterFox just pushed a new update for me and works with 3.0.1.

You can also download the latest dev-build of Tab Mix Plus, modify the install.rdf file to work with this and install it.

musicphreke

The update whacked three of my previously functioning add-ons.

Craig720

@patrickjdub2: I use this tool for the exact same thing..

As long as the extension has already updated to any 3.* version, you will more likely be able to get it to work. I would not recommend for FF2 add-ons, but so far I have not had really any issues with FF3* add-ons.

jimredbaron

Tried installing it, and now every time I try to open FF I get the following message "Firefox couldd not open this item because of a failure in the chrome registration. Please contact the author about this problem"
Crap.

suburbancowboy

I'm somewhat mystified. I use FF3 on three machines, two run Kubuntu, 1 (my office) runs WinXP. I have very few of the issues described here. The worst issue is page shaking on the WinXP machine.

Four extensions are currently unavailable: Evernote, Firebug, DogEars and Mozilla Archive Format.

a_wanderer

I am still having cookie problems.

anthonylitz

anycolor doesnt work with it

fullyrandomtandem

@nerdly: Honestly, I don't use it.

my question is, does this screw up Mouse Gestures, b/c I LOVE that extension.

arkitect75

@gawyn210:

Scan through the comments. There are several posts with a solution for the Tab Mix Plus issue.

jsmorley

My tab mix plus isn't working with 3.0! Does any one know why? looks like there's no reason for me not to upgrade to 3.1, but I think I'll wait to see if there is an answer to my tab mix problem in 3.0.

gawyn210

BTW - Those instructions are for Vista, if you are still on XP the bookmarks will be in C:\Program Files\Mozilla\Firefox\Profiles\xxxxxx.default

Also, after you uninstall you might want to be sure to remove the whole ..\Firefox directory to be sure you get rid of old stuff messing you up. In Vista it's a bit tricky to get rid of C:\Users\yourname\AppData\Roaming\Mozilla\Firefox\ since it is hidden by default, but you can turn on "show hidden files and folders" in folder options.

jsmorley

TMP DOES work on 3.0.1. Install the following and it will work:

[mark.bockenstedt.net]

jackospade

@gawyn210: I already mentioned how to fix that. Go download the latest dev-build from [tmp.garyr.net] and once you've downloaded it, open with something like 7-Zip/WinRar/Winzip and edit the install.rdf file [change MaxVersion line be something like 4.0 or something like that]. Works like a charm for me.

musicphreke

Looks like they added a new feature with this version for Ctrl+Tab showing previews of the tabs and stuff. It doesn't seem to work for me, though, but it's probably Tab Mix Plus causing it or something.

musicphreke

@willisja: I also downgraded to FF2 after FF3 crashed multiple times per day whenever I had a Gmail tab open (or when I closed Gmail's tab!). Your experience isn't unique -- just google "Firefox 3 Gmail crash" to see what I mean.

Arthaey

used the Nightly Tester Tools Extension that @Rae: suggested.

everything works great :) Overrode the Tab Mix Plus incompatibilty xD

thanks!

Soulgenesis

This has already been said but it bears repeating since clearly a lot of people have missed it.

The easiest way get your add-ons working again if they say they're incompatible, install Nightly Tester tools and use the "Override Compatibility" option that it adds to the addons dialog.

[addons.mozilla.org]

Talthybius

@musicphreke:

I disabled Tab Mix Plus, and all I get when I CTRL-Tab is the usual switching between tabs. No preview or anything.

jsmorley

After using FF for a couple of years or so I'm now having to try Safari - FF3 just doesn't work, period.

Patrick Dodds

Looks like 3.01 fails Acid2 (whereas 3.0 passed).

Rae

Paste and Go Notes.

I figured it out with the following:
(1) Go to where your extensions are located..
for example:
C:\Documents and Settings\(UserID)\Application Data\Mozilla\Firefox\Profiles\zyyz6m23.default\extensions\pasteandgo2@holio.lin
(2) Make a copy of the folder: pasteandgo2@holio.lin
(3) Locate the install.rdf file..
(4) Open it in your favorite editor..
(5) Find the line: <em:maxVersion>2.0.0*</em:maxVersion>
(6) Change it to: <em:maxVersion>3.0.*</em:maxVersion>
(7) I was prompted to uninstall it, but on restart it prompted me to enable and work with it.

Cool!

Thanks,

Kent

kdyer

My add-ons are all fine after the upgrade. Now, my themes, that's another story. I got 2 out of 4 disabled on my work laptop and some 5 out of 8 on my home PC. Not that it's a big deal anyway, as I've been using the default theme since I upgraded to FFx 3.0, but hopefully, these incompatibilities will get fixed soon.

apocalypsofacto

Maaaaan!! WTF!!! FF3 is a mess and I'm using Opera till I decide to rollback to 2.

Are L.H. users being used as Beta testers now?? This article should be amended or taken down before someone else gets everything reset or borked.

Hawaiibadboy

I saw this yesterday, but didn't manually run an update because of issues noted here in the comments. I wasn't having major problems before though, either. At work today, I was notified that an update was available, and it offered to show me what add-ons were incompatible with the update. It was only Tab Mix Plus, so I web searched and found that an update for it is available. I installed that, then tried the 3.0.1 update, and it didn't point out any conflicts, so I installed it. I'll have to check at home, where I have more add-ons, and see what's incompatible and what has updates before I run an upgrade there.

Dronak

My firefox won't even load. I have reinstalled the new app 3 separate times, rebooted the computer, and nothing. The task manager does not say that I am even running the firefox.exe. Any insights would be greatly appreciated.

acekaye

That MRI LocalTechInstall seems to override the incompatibilities. Woohoo! Good call!

the_Sleepwalker

firefox is getting worse & worse...crashed when i had 2 print out a important doc...thanks firefox! now i can't get it back =.=

Arsenal6

Funny, because as I was opening this blog.. My Firefox 3.0.1 crashed!!

Ken

By reading all the comments you'll understand why I never switched to FireFoxtrot...sigh

JDonner

Where have you been all my life Mr. Tech! (Thanks patrickjdub2 & DasLife). Fixed TMP no problem.

Itsallballbearings

In contrast to all the horror stories in these comments I didn't lose any of my extensions in this update. I'll list them in case anyone is hesitant about updating thinking any of these will break. I'm running Vista SP1.

Adblock Plus 0.7.5.5
Customize Google 0.72
Download Statusbar 0.9.6.3
Flagfox 3.2.7
ForecastFox 0.9.7.7
Gmail Manager 0.5.5
Move Media Player 1.0.0.07103010
NoScript 1.7.7 (Updated at the same time as Firefox)
Organize Status Bar 0.6.2 (Tweaked to run on FF 3)
PDF Download 1.0.1.2
PicLens 1.7.0.3459 (Contrary to soulcabbage's comment above, it works fine)
Tiny Menu 1.4.9

HardcoreLilly

@rraheja: Interestingly, my RTM for Gmail extension wasn't flagged as incompatible and is working. Google Gears won't work, however (no biggie) and, as others have mentioned, Tab Mix Plus was flagged incompatible (but that's working again, as I downloaded MR Tech Toolkit and turned off incompatibility checking and TMP is working fine (so far). All of my "Better..." extensions were left unflagged and appear to be working as expected. TMP was the big problem for me, but, again, it seems okay after turning off the compatibility checking for now.

mattsen

Firefox's work where other browsers don't but it's not going hand to hand with windows vista and other sites that it's easy to suef using other browsers, We use it for our online see link here [www.lvhsystems.com]

lvhsystems

Hell. Please, double check before post!
Tab Mix Plus aren't working!

dimaer

There is another addon that allows you to override the compatibility warnings, and it worked for me since I use TabMixPlus, which is now working with the 3.0.1 update. The addon is Nightly Tester Tools, you can find it here https://addons.mozilla.org/en-US/firefox/addon/6543 After you install it and restart Firefox, go to Tools\Addons\ and you'll see an "override all compatibility" button, which you press and keep going. Things then work OK. This was covered in Lifehacker sometime back...

UmitTullus

Two major Add-ons (for me atleast) stop working: 1) DAP Integration 2) gDocBar Harsh

TammyMozie

Does this update fix the problem of embedded WMA movies moving when I scroll up or down on the web page. This was a problem before and now its a problem again.

Zillas_Tipster

Oh,at least the Google Gears and tab mix can't work after this update

ForrestMerope

I feel like all my add-ons finally started working on 3.0, and now this.

kirksucks

My Better LifeHacker addon isn't working. Help?

Trashtastic

My Tab Mix Plus work-around doesn't even work now. Argh!

dluxfresh

I'm so happy to find this post! But I wish I found it before I agreed to download the upgrade. Sadly, NONE of my add-ons are working. I used:

KeyScrambler
Organize Status Bar
TwitterFox
Tree Style Tab (LOVE this one!)
Tiny Menu (again, great to grab more real estate)
Quick Restart
Greasemonkey
FoxClocks
Fierr
All-in-One Sidebar (another one I use frequently)

Now it's just a boring, standard browser. I hope this gets corrected soon.

HoodGeek

Does anyone know if installing this update will change any tweaking I've done to 3.0 through about:config?

Papabambam

Tab miw plus works well if you use this version:

[tmp.garyr.net]

Jahmon

When I go to Tools>add ons, nothing works. I can't uninstall, disable, or work on the options for any of them. It keeps saying "Restart Firefox to complete your changes". Obviously I've restarted many, many times, but it hasn't changed. The *only* button that works is the little x in the corner, and god help me if I click on anything else, because then even won't work.

I used to love Firefox, but I've been having so many crashes and problems lately (with 2 and 3) that I'm seriously thinking about going back to IE.

Suzi

Anyone manage to get the nested comments with the better lifehacker extension working?

More stable? That's a laugh. FF 3.0.1 crashes 5 to 10 times a day and more when viewing ip security cameras like this one [64.53.55.34]

I had to give up and use Netscape 9.0.0.6 that I never deleted after it stopped updating.

Sure hope they stop lying and fix it soon. Other tan that I love it.

Glad to see other people out there are having issues with FF3 like myself, I thought I was the only one.

Nightly Tester Tools works for me sometimes and sometimes I just keep getting asked to restart FF to install extensions. God, I had FF2

cont... actually hit submit

I had FF2 running so great, now it feels like I have a classic car sitting in the garage and I can't drive it around because it needs fixed even thought most things on the car are easy to fix, I can't find any of the parts anywhere. I'm thinking rollback time.

My ff3.0.1 is working great. I am just looking for Minimize to try and then I will have all the extensions I was using prior
