Firefox is due to release an eighth Firefox 4 beta. Not to be confused with a fourth Firefox 8 beta.
The latest test version of Firefox 4 – due for an official debut next year – was scheduled to go live on Tuesday. Mozilla hasn't added any new tools, but according to the release notes, the open sourcers have polished a few things, including the browser's Sync service, which synchronizes bookmarks, history, and other setting across multiple devices; its WebGL 3D rendering tech; and its add-ons manager.
The beta also fixes hundreds of bugs. You can eventually download it here for Windows, Mac, and Linux. As of Tuesday evening Pacific time, the download button had not yet been switched from beta 7 to beta 8.
The first "feature complete" Firefox beta was released in early November. This was originally scheduled for release on September 17, and as it was pushed back, Mozilla also delayed the release of the stable browser. The official Firefox 4 is now due in "early 2011." ®
