UPDATE: Firefox 4.0 Beta 11 is now available for download.   Although the eleventh beta for Firefox 4.0 is not quite here yet, the vast majority of the work for this particular development milestone has already been completed and the release is extremely close.

Mozilla was considering making Firefox 4.0 Beta 11 available to testers either today or tomorrow at the latest, but it appears that the open source browser vendor finally decided to deliver the bits on February 8.

“QA has signed off on Firefox 4 beta 11. We intend to push it to mirrors tonight / tomorrow morning PST and release to the beta audience tomorrow, 2011-02-08,” revealed Christian Legnitto, Firefox release manager for Mozilla.

At the time of this article, Firefox 4.0 Beta 11 was not available for download, however, make sure to keep your eyes on this space and I’ll provide an update as soon as the Build goes live.

Mozilla only recently offered early adopters Firefox 4.0 Beta 10 for testing, and is now in the final stages of the development process.

According to the plans made public so far, Firefox 4.0 Beta 11 will be followed by Beta 12. Mozilla intends to ship a total of a dozen Beta releases for the next iteration of its open source browser, but at the same time, nothing is set in stone, and yet another Beta could follow, although chances of this actually happening are extremely slim.

“Firefox 4 beta 12 [has] no hard schedule. We're trying to get all betaN hardblockers done by this Friday, which would put us in position to build beta 12 at the start of next week.

“There are 17 betaN hardblockers with patches, which means there are only ~2 that don't have patches.

“We still reserve the right to have another beta if needed, but are driving to have beta 12 be the last. Again, highly dependent on remaining work, new items found during beta 11, etc.,” Legnitto added.
