It's slow progress over at Mozilla with regards to Firefox 4 beta. The next beta, which will be the twelfth, has been delayed.
Oh, and Mozilla are keeping their options open for another beta if necessary. Here are the details, straight from the Mozilla dev mailing list:
- We will not be building a Firefox 4 beta today
- We will wait for the few remaining betaN hardblockers before building Firefox 4 beta 12
- As of now, beta 12 is the last planned beta
- We reserve the right to have a beta 13 if issues found in beta 12 need additional coverage before a release candidate (RC)
Five bugs are holding back the beta, one of which has the highest rating of 'major,' two are listed as 'critical' and three are 'normal.'
Given this new delay it is highly unlikely that Firefox 4 will ship this month.
