Mozilla has confirmed that it will add another beta to the Firefox 3 .1 development schedule, a move that will push the browser's ship date to the second quarter or later.
The decision was not unexpected. Last month, Shaver said that bugs in TraceMonkey had slowed the development pace, which in turn had kicked the browser's release into next quarter . He also said that developers were considering a fourth beta.
Shaver's decision to push out Beta 3, come hell or high water, followed comments by a few Mozilla developers who wondered whether it's smart to hold up Firefox for TraceMonkey fixes.
