I thought Firefox problem was fixed due to blocked by Firewall, but it didn't work! Msg. Firefox has stopped working still getting it! Wish there was a fix?

I continually get the message: Firefox has stopped working! I have uninstalled & reinstalled Firefox per help from this forum followed the instructions. That didn't work! Then I got help from someone else saying go to your Firewall & unblock Mozilla. I did that & thought it fixed the problem but just opened & closed Firefox & got the same message again! If there is a fix for this please let me know??? If its possible to go back to the older version please let me know--I did not have this problem until I updated to the latest version!! I have disabled Photobucket addon, Real Arcade that didn't help. I have Vista home 32 bit.

Does the problem occur at a particular time or on particular sites? For example:

  • Starting up to the built-in Firefox home page
  • Starting up to another home page
  • Starting up and restoring windows/tabs from a previous session
  • Shutting down
  • Other...

Thanks for any additional info you can provide.

Do you recall what version you had previously, i.e., Firefox 20.0 or Firefox 19.0.2?

Firefox 21 is expected to be released on Tuesday, so if you think it might be specific to Firefox 20.0.1, you could install the very-nearly-final version of Firefox 21 from here: http://www.mozilla.org/en-US/firefox/beta/

It wouldn't be a bad idea to make a backup of your current Firefox settings folder first, just in case something goes wrong. This article has tips on that: Back up and restore information in Firefox profiles.
