How to troubleshoot the error code "Windows cannot find 'firefox'. make sure you typed the name correctly
I started to get this error message that came up every five minutes and Firefox would crash. I then unistalled Firefox, cleaned the cache and history,and then rebooted the computer. When I try to install Firefox it pulls up this error message as well as now it is every two minutes that the error message appears. How do I trouble shoot the error message and reinstall Firefox on my computer. I am using Windows 8.1.

Do a clean reinstall of the current Firefox release and delete the Firefox program folder before installing a fresh copy of the current Firefox release.
- Download the Firefox installer and save the file to the desktop
*https://www.mozilla.org/en-US/firefox/all/
If possible uninstall your current Firefox version to cleanup the Windows Registry and settings in security software.
- Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- It is important to delete the Firefox program folder to remove all the files and make sure there are no problems with files that were leftover after uninstalling.

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you uninstall and reinstall or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then create a new profile to test if your current profile is causing the problem.
