Firefox is a outstanding web browser whose functionality can be easily extended by virtually unlimited myriad of innovative and exciting plug-ins and extensions. However, the poor programming of certain “add-ins” or even software conflict among them can affect the stability of Firefox and may cause repeated crash . Although the user can generally fix this issue by disabling the problematic “add-in”, there may be time where the problem continue to persist. In this case, the only way is to reinstall FireFox with the following notable steps.
Problem: Crash still persist after FireFox reinstall
If after uninstalling and reinstalling Firefox, user still find that the crash persists, it means that Firefox is reusing previous configuration setting which may still load the problematic “add-in”. Note that FireFox does not overwrite previous configuration setting but rather reusing the exist configuration.
Solution: Remove Firefox in User’s directories prior to reinstallation
Prior to reinstalling FireFox, make sure its configuration and add-in directories are removed. The configuration and add-in directories do not reside in FireFox’s application directory but in the user’s own directory.
For Windows Vista, delete the following user’s directories which contains the plug-ins extensions and Firefox setting.
After reinstallation, user can then operate over the “clean” state of FireFox.
