Was finally ready to start working with Firefox 4 on my new Windows 7 computer. Went to download Firefox 4 Beta 8 and was offered Firefox 4 Beta 9. Mozilla released the ninth beta for Firefox 4.0 on January 14th. This is a regular beta release and is being made available for testing purposes only. New stuff in this Beta 9 release:
- Overhaul of the bookmarks and history code, enabling faster bookmarking and startup performance
- Per-compartment garbage collection is now enabled, reducing work done during complex animations
- See the complete changelist from the previous beta
For more info see the release notes for Firefox 4 Beta 9. The next planned release is the Beta 10 then moving in to the Release Candidate (RC) builds.
