Firefox 64-Bit For Windows Finally Available

Firefox 64-Bit For Windows Finally Available

It has been a long wait but Mozilla has finally released the 64-bit version of the its popular Firefox browser for Windows 7 and above operating systems. Here’s what you need to know and how you can get it.

The Firefox browser for Windows has always been a 32-bit software and after years of developing and testing, Mozilla is now confident enough to release the 64-bit version that is more compatible with modern day processors.

The company has warned that there is limited support for plugins on Firefox 64-bit but this is by design:

[U]sers will notice that certain sites requiring plugins that worked in previous 32-bit versions of Firefox might not work in this 64-bit version. As we’ve shared previously, Mozilla intends to remove support for most NPAPI plugins in Firefox by the end of 2016.

You can download and install Firefox 64-bit for Windows on the Firefox All Systems website.

  • Other than the highly scientific ‘Suck it and see’ method, anyone know how to figure out which plugins are NPAPI-based and won’t work with Firefox 64?

    • I used Mozbackup to save the 32bit version and then applied it to the new 64bit version. All my addons worked fine and I have a lot of ’em.

  • I assume it is Waterfox being called FF…
    It came in with my WF profile
    Problem with both is the Open Tabs bar is above the Location and Bookmarks bar.
    I will stay with Cyberfox which has the Open Tabs in correct place at top of open page.
    I fail to understand why FF chooses that layout … customise does not appear to allow a change. Cyberfox does run all Addons I like and it seems to use the similar of Memory as Firefox
