After I upgraded my firefox to version 2.0.0.2, it crashed frequently.
Tried to roll back to version 2.0.0.1, no luck at all.
I decided to roll back at 2.0 which is successful.
Download the 2.0 at http://releases.mozilla.org/pub/mozilla.org/firefox/releases/2.0/win32/en-US/Firefox%20Setup%202.0.exe
Uninstall the 2.0.0.2.
Use Registry Cleaner such as WINASO Registry Optimizer http://www.winaso.com/ to clean up registry.
Install the firefox version 2.0
and voila….it doesn’t crash anymore.
