Mozilla has finally released Firefox 3.5 Beta, the latest version of its web browser that has been delayed several times already this year.
As it usually does, Mozilla warned users that Beta 4 is suitable for testing only.
"Firefox 3.5 Beta 4 is a public preview release intended for developer testing and community feedback," said Beltzner. We recommend that you read the release notes and known issues before installing this beta."
Beta 4 is the first major milestone of Mozilla's new browser to carry the '3.5' moniker; originally, the upgrade was called Firefox 3.1, but the company decided it had added enough new features to justify the larger bump in version number from last summer's Firefox 3.0.
Although Mozilla said much earlier in the Firefox 3.5 process that it would ship a limited number of betas before moving on to a 'release candidate', it's now unclear what Mozilla's next step will be.
In 2008, the company issued the last beta of Firefox 3.0 in early April, and the final version in mid-June. Assuming Firefox 3.5's pace is similar, Mozilla should ship Firefox 3.5 sometime in early July.
Firefox 3.5 Beta 4 can be downloaded for Windows, Mac OS X and Linux in 63 different languages from Mozilla's site. Users already running Beta 3 will be notified of the available update in the next 48 hours.
