Firefox 10 Releases Today, Fixes Add-On Compatibility Issuesby Andrew Cunningham on January 31, 2012 12:40 PM EST
Firefox 10 is due to release today, continuing Mozilla's commitment to the six-week release cycle it switched to last year. As usual with these rapid-release browsers, Firefox 10 brings a couple of features you'll probably notice and a few more that you probably won't. The browser is available for Windows XP, Vista, and 7, Intel versions of Mac OS X 10.5, 10.6, and 10.7, and most flavors of Linux.
Firefox 10's banner feature is a tweak designed to fix add-on compatibility - most add-ons compatible with Firefox version 4 and later will now automatically be marked as compatible by the browser without any additional updates from the add-on's developer. This is true both of add-ons downloaded from Mozilla's repository, or add-ons installed from elsewhere on the Internet. This was done to ease the pain of upgrading for heavy add-on users, and to make way for Mozilla's silent Firefox updater, which is tentatively scheduled to land in June with the release of Firefox 13.
Mozilla has also hidden the browser's forward button unless it can actually be used, implemented anti-aliasing for WebGL, added support for CSS3 3D transforms, added full-screen APIs to allow for full-screen web apps (though still no official support for Lion's Full Screen mode), and a few other small feature and bug changes.
FF10 is also the first release of the browser to be offered as an "Extended Support Release" or ESR, which will be offered as a separate download - as we reported earlier this month, the ESRs will be good for a year, and will keep the same major version number and rendering engine while being kept current with security and bug fixes. The ESR is intended to replace Firefox 3.6, which has been patched continuously as Firefoxes 4 through 9 have been end-of-lifed, and is meant to placate enterprise administrators and others upset by the new rapid release cycle. Firefox 3.6 is tentatively scheduled to be discontinued on April 24, so if you've stuck by it for the last year you should begin testing the new version soon.
