Basically I downloaded Firefox 4 when it was a beta and now after it's been released and everytime I double click the shortcut or the direct link in the start menu and it shows my mouse with the loading icon and then it pops up the "Mozilla Crash Reporter" and I've submitted multiple reports and got nothing back and I now can't revert back to pre-4.0 Firefox to even just use it while the problem is rectified.

Your best bet would be to uninstall the BETA and install the actual release, instructions as follows.

  • Go to Download Firefox 4.0 and download a fresh installation file to the desktop. If necessary, download the file with IE8 or 9, but choose to save it to your desktop when you see the prompt.
  • Hit CTRL+SHIFT+ESC to bring up Task Manager, go to the Processes list and see if you can find firefox.exe running in there. If you do, right click it and choose "Kill Process".
  • Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
  • Then reboot and delete the folder called Mozilla Firefox at this location: C:\Program Files\Mozilla Firefox
  • Finally run the installation file you downloaded to the desktop earlier.

If you prefer to install the previous secure version which is v3.6.16, use the following link, otherwise the procedure is the same: Download Firefox v3.6.16
