Mozilla has unveiled the final beta of Firefox 3.0 and will move on to the release candidate stage by freezing changes as early as next week.
Beta 5's release was delayed somewhat by the discovery last week of a serious bug in the Mac version of the browser, which required fixing before Mozilla would sign off on the preview.
Updated release notes also published today noted that Beta 5 includes more than 750 changes since the roll out of Beta 4 three weeks ago.
In notes from a Monday meeting that have been posted to the Mozilla Web site, the code-freeze date for the release candidate has been set as next Tuesday.
Mike Schroepfer, Mozilla's vice president of engineering, said last week that he expects Firefox 3.0 to run through three release candidates before the final version. Mozilla has targeted June for delivering the browser.
Firefox 3 Beta 4 can be downloaded for Windows, Mac OS X and Linux in 40 languages from Mozilla's site .
However, as has been its practice with every beta, Mozilla again warned casual users against using the preview. "Firefox 3 Beta 5 is a developer preview release of Mozilla's next generation Firefox browser and is being made available for testing purposes only," the release notes read.
