Well, Firefox definitely should not uninstall itself... you might want to check for other explanations, particularly questionable software. Our support article lists tools other Firefox users have found helpful: Troubleshoot Firefox issues caused by malware. These programs are free and take some time to run. If they seem to finish quickly and require a payment to actually do anything, your system may have a more serious infection. In that case, please try the specialized forums listed in the article.

The user profiles are kept in a folder in the user folder on the computer.

Use the full installer above. This should overwrite the old FF folder.

If you are using Windows, run most or all of these programs.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
