Mozilla revoked its plans to roll out the new browser Firefox 4 next month. According to a new schedule the browser will not arrive until "early 2011."

"As discussed in today’s Firefox delivery meeting, release candidate builds are now scheduled to ship in early 2011, with the final GA release shortly after," a Mozilla representative said.

Firefox 4 is now in its sixth beta release. Beta 7 — the "feature complete" beta — was due on September 17, but according to Mozilla's schedule, it will not arrive until November.

Mozilla's Firefox headman Mike Beltzner also discussed the change on the Mozilla development mailing list. "Based on the delays in completing the 'feature complete' Beta 7 milestone against which our Add-on developers and third-party software developers can develop, as well as considering the amount of work remaining to prepare Firefox 4 for final release, we have revised our beta and release candidate schedule," he said.

"Please note that, as always, this schedule is subject to change based on feedback from users and community members."
