Windows/Mac/Linux: The latest version of Firefox is available for download, and with it comes the ability to synchronise your add-ons across desktops and operating systems with add-on sync. Firefox 11 is in line with Mozilla's new Chrome-like rapid-release schedule, and aside from a few new developer tools, add-on sync is the only major new feature available in the new version.
Once enabled, Firefox Sync will also give you the option to ensure your add-ons are available on all of your computers.
In addition to add-on sync, the new version marks most add-ons compatible by default, regardless of the extension's version number. Developers get access to a few new tools in Firefox 11, including "Tilt", a 3D page inspector and an on-the-fly CSS editor that will allow you to edit stylesheets directly in-browser.
Firefox 11 is available to download now at the link below, or you can use the browser's in-app updater to download it.
