The fine folks at Mozilla have released Firefox 0.9.1 for mass consumption. The difference between this release and the 0.9 release is mainly a few critical bug fixes and some very nice default theme updates. I plan on writing a little review of this in the next few days if I get the time.
In the meantime, please download the new version! Make sure you uninstall your old version before installing the new one. Don’t worry, your bookmarks and settings will be saved regardless.
