Firefox 4.0 Beta 7 Now Available and Feature Complete

The new feature complete beta version of Firefox 4.0 is available for download and is faster than ever. Even better is the news that the Add-on APIs are also stable now, so you should soon see your favorite extensions updating for 4.0.

Here is what is new/fully active in Beta 7:

  • The JagerMonkey JIT compiler has been incorporated along with enhancements to TraceMonkey JIT and the SpiderMonkey interpreter.
  • Hardware-accelerated graphics (compositing)
  • WebGL for rendering 3D graphics
  • Support for the OpenType font format
  • Improved HTML5 forms

Add all of that in with other 4.0 features such as Firefox Sync, Panorama, App Tabs, & the new Add-ons Manager and you have a totally awesome browser. With the feature set now stabilized, all that is left to do is make any needed refinements, fix bugs, and work on problems that cause the browser to crash.

Curious how the new beta compares to other versions of Firefox? Then feast your eyes on these JavaScript benchmark results.

    I’ve been using Firefox 4 beta 7 on OS X since last night and absolutely love it. I’m really glad they got rid of the status bar. The only thing I wasn’t crazy about was the stop/reload button being part of the address bar. Thankfully you can move it elsewhere.

    How does it fair in the Acid3 test?

  3. Dave


    It scores 97/100

    Not bad. I like it a lot, but the hardware acceleration really makes text look bad. I turned it off, and the text is much better. I read that is meant to happen. Really? Bad text rendering? Oh well.

  5. ArashiX

    Tried it out earlier today. Quick, functional, and aesthetically pleasing to the eye (really like the UI for it). Can’t wait for the official release.

    @David Levine

    I’m also looking for a way to move back the refresh/stop button to it’s original place, how did you do it ?

  7. rino

    @BobbyPhoenix, you don’t have to. just go to about:config and toggle the value of “property gfx.direct2d.disabled” to true.

  8. AsianAngel

    @Alendra – Right click in the toolbar area and select Customise. Once you have done that the Refresh/Stop Button will be separated from the Address Bar. Drag it to where you want it located and close the Customise Window to finish up. ^_^

    firefox without the status bar looks like a someone forgot his pants.

    head on to a.m.o. and install “Status-4-evar” extension. after that, enable the “addon toolbar”.

    About moving refresh/stop button to it’s original place…

    TO UNIFY BOTH BUTTONS in only one: You will have to put the two buttons in a certain order (from left to right): …
    first, the Refresh button.

    If you put the buttons in the order (Stop and Refresh), it not “unify” on only one button.

    Oh, sorry about my English… I’m brazilian. :)

    Wow. I read for so long on how to make both work together, and everything I tried failed. Your solution worked on the first try, so now I get all the benefits of hardware acceleration WITH readable fonts. Thank you!

  12. Bob1001

    Thanks Geek, I will update my version from Beta 6 to Beta 7 – now!

  13. Alendra

    Thanks AsianAngel :)

    @rino Thanks for that extension, I missed status at the bottom of the screen ! :)

    Is that damned search-as-you-type/see EVERY website you ever went to (or didn’t!) address bar still there? And if it is, will Old Location Bar work on 4 beta?

    That thing nearly drove me to a different browser until I found a decent
    add-on to fix it.

  15. Antje

    I cannot wait for the new release, but I am a bit anxious to see them address that last three failed tests in acid3. If they did it would be awesomesaurus.

  16. Camilo Martin

    @Antje there’s a lot of stuff that the Acid3 test won’t test, it’s not a complete test of all features a browser can have. Besides 97/100 is good enough for me! :D

    But I’m curious. the gfx.direct2d.disabled property isn’t going to disable the whole hardware acceleration?

    And I know it IS possible to render hardware-accelerated Cleartype. Microsoft just fixed it in the release of Visual Studio 2010 (before that, WPF’s text rendering did look like crap).

    i don’t get why firefox is all the rage. i use it as much as chrome, but chrome is still faster.
    never was a firefox guy – only use if for business. saved the fastest one for personal use XP;

    How do you get the Firefox logo instead of the name? Running B7 on Windows 7

  19. AsianAngel

    @Tylor Lavoie – I used this extension to convert the menu access over to the Firefox logo button. ^_^

    Cool … this should be useful particularly as I tend to have to use older or lower-power machines. But I also make much use of seperate refresh/stop and the status bar. Can they be set to v3 behaviour by an option, or is the default the only way?

  21. AsianAngel

    @tahrey – These two commenters have solutions for both of the UI questions you have. ^_^

    For a solution to the Stop and Refresh buttons being combined, see Overlord’s comment above.

    For the Status Bar issue, see rino’s comment above that mentions the Status-4-ever extension.
