Yesteday, I downgraded my Mozilla Firefox installation to 1.5. My main reason is that it crashed so many times. I know, Mozilla Firefox 2.0 has great new features. But the previous version (I use 188.8.131.52 now) has all features I need.
When I switched to Firefox 2.0, I have no problems with the extensions. Most extensions have been updated; compatible with Firefox latest version.
I will stay with 184.108.40.206 for now, and I haven’t experienced crashed browser until now.
FEBE backs up your extensions, themes, and (optionally) your bookmarks, preferences, cookies. and much more. In fact, it goes beyond just backing up — It will actually rebuild your extensions individually into installable .xpi files. Now you can easily synchronize your office and home browsers. A great tool; if you need to roll back.
Some notes why switching to Firefox.
