Firefox 4 Beta 9 now out fixing 661 bugs.
Mozilla today officially released Firefox 4 Beta 9 and it's a big improvement over previous betas and a parsec beyond the Firefox 3.6.x experience.
At this stage, after months of development, Mozilla developers are clearly nearing the end of this development marathon. If this had been Google, the 9 Betas would like have been broken up in to 5 (or more) stable releases -- there are just sooo many new features.
For Beta 9, by my count of the buglist, there are some 661 items that were fixed for this beta.
