Firefox 4 now available

Summary: Firefox 4 finally makes its debut.

Paula Rooney

By for Linux and Open Source |

The Mozilla team this morning officially released the public version of Firefox 4.

The update for Firefox 3.6 users will be available at roughly 10:20 a.m., developers said moments ago.

Version 4 desktop release features a redesigned user interface, new JavaScript engine, hardware acceleration, new synchronization capabilities and up to date support for important web technologies such as HTML5 and WebGL.

The final code is based essentially on the first release candidate that shipped March 9, sans a few fixes. Bugs that surfaced after RC1 shipped were addressed in a follow up release candidate 2 for Windows, OSX and Linux that slipped out late last week.

The team plans to ship out a quick fix patch code named "Anteater" within the next two weeks if necessary. Then, a "Macaw" update is expected two to three weeks from today that will incorporate other fixes discovered during the first month of use.

The beta test cycle began in June.

It's not clear when Firefox 4 Mobile will be shipping. Firefox 4 for the iPhone? Mozilla developers could not say because they claim they lack info or code needed from Apple.

      It cant be any worse than a 12 hour day trying to get a new xp install to update, only to have a blue screen of death from the ati driver that microsoft provided. Or having to reconfigure another computer with basically the same issue, those automatic updates may be convenient, but gods only knows what's in em. Don't download microsoft ati driver updates, they break your machine!!!!!

        Actually I don't blame MS for those updates as they have worked fine for me for many years now. I blame AMD's hardware or better yet the drivers they release which are poorly coded. Also take note that the driver MS serves you comes from AMD not Microsoft.

  • I'll look at it but I think I will stick with Chrome.

    There are two reasons I like Chrome:
    1. I like the simplicity of the UI
    2. It has never been successfully pwn'd at CanSecWest and the others have. Charlie Miller who has been nasty to Safari said that he thought Chrome would be the hardest to attack.

    • But Google will never let you get rid of their ad-spying, which is actually

      @DevGuy_z: ... the core idea of whole Chrome thing, as well as any other projects which Google provides "for free".<br><br><b>You will be fed with these hellish flashing/blinking Flash advertisements forever.</b>

  • Sweet!!!

    Upgrade time!!! Eat dust Microsoft! IE is only usable for one Operating System, and that is Vista and Vista Service Pack 7. Lame!

  • No use for Firefox 4... Will stick with 3.6.15

    I don't know about the Windows version, but they sure screwed up flash support in 4 on the Mac side. It works, but I might as well be trying to do flash on an Android phone (yes, I have one). Slow, choppy, horrible. Have tried it on three dual core Mac machines (all between a year and 18 months old) and it's horrible...

    I do have to say that they did significantly improve Java support, but they sure did leave Flash by the wayside in doing so...
