Mozilla has released Firefox 4 Beta 12. The new beta build comes less than three weeks after the Beta 11 release, and as far as we can see this is mainly just a bug fix release. The company says this release delivers improved performance and responsiveness when watching videos on websites. For more information, check out the release notes.
If you're already running a previous beta of Firefox 4 you should see an automatic update soon. Alternatively, you can download Beta 12 directly for Windows, Mac OS X, and Linux 32-bit/64-bit. The beta supports 77 languages.
Mozilla was originally planning on having Firefox 4 out by the end of last year, but it has had to delay the release multiple times. The company has fixed more than 7,000 bugs since the first beta release. The RC is next, followed by a final release.
Mozilla has been struggling to get Firefox 4.0 out the door. As a result, the company has announced that in 2011, not only will we see Firefox 4.0, but we will also see Firefox 5.0, Firefox 6.0, and Firefox 7.0.
