Found 0 results for how do I UNINSTALL Firefox 9.0.1? I Installed it last night and Firefox has crashed maybe 20 times since then. The previous version almost never crashed. Please help

Since installing Firefox 9.0.1 LAST night on my iMac, which is running OSX v. 10.5.8, Firefox is now crashing every few minutes. It usually happens as I go from one website to another -- when I click on a bookmarked website from my bookmarks, Firefox crashes just as the next website is coming up. I have NEVER had this problem with Firefox before. I need to uninstall and revert to the previous version of Firefox, but OSX doesn't have an easy "revert to previous configuration" routine. Or... please send out a fix for 9.0.1 (assuming others are having the same problem) right away.

Might not be related to your problem but some of your Plugins are out-dated

  • Update All your Firefox Plugins -> https://www.mozilla.org/en-US/plugincheck/
  • When Downloading Plugins Update setup files, Remove Checkmark from Downloading other Optional Softwares with your Plugins (e.g. Toolbars, McAfee, Google Chrome, etc.)

Thank you mha007. Actually, Verdi had solved the problem about 10 days ago. It was another Plug-in, Showcase, that was incompatible with the newest Firefox, so he told me to disable it, and that worked instantly. The other day, though, Firefox again started constantly crashing. This time I looked and found -- as you suggest -- another outdated plugin, in this case Silverlight. Don't know why it took ten days to start causing a problem, but as soon as I disabled it, everything was back to normal. I have NEVER had such problems with any new versions of Firefox, and I've been using it for ages, so this was pretty disconcerting to see how problematic the new version was.
