For those keeping track, Firefox 3.5.17 & 3.6.14 were scheduled to be released back on February 8th. This date later got pushed back to February 14th. Finally today, February 18th Mozilla updated the release page removing a projected release date. So what’s with the delays? Unlike Firefox 4 Beta 12, this one took a bit of hunting around to find more info. Finally found some information from the February 16th Firefox/Gecko Delivery Meeting notes. The problem is with Firefox 3.6.14 and therefore is also delaying the release of Firefox 3.5.17 (as well as Thunderbird 3.1.8).
The issue is a pesky ‘crash upon startup’ bug (63389) on Firefox 3.6.14 (and possibly Thunderbird 3.1.8). This critical bug is actually in the update process from 3.6.13 to 3.6.14 and seems to be taking a bit longer than expected to get squashed. Build 3 was released today so there may be a patch in the works. However, given Monday is a holiday (President’s Day for those outside the US) and there is likely still more testing to be done, it may be not until late next week before these updates get released.
