Mozilla was crashing every few seconds and I couldn't install the update. I removed the old to install the new and now I can't install - getting error messages that close themselves.

When I try to install I receive this message:

"Firefox has stopped working A problem caused the program to stop working correctly. Windows will clsoe the program and notify you if a solution is available."

This happens when I select RUN to install Firefox 9.0.1

I removed the old version because it was crashing everytime I tried to use it and it wouldn't let me update with the new.

I HATE IE, and need my Firefox back --- I am dead in the water for work without it.

Did you verify that the Firefox program folder (C:\Program Files\Mozilla Firefox\) is completely gone?

Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible.

  • Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
