Well...the title or were the question should be says it all, it happened not to long ago like 5 min. ago after a routine up date firefox didn't open. I figured well this has happened before so I went through the usual and restarted my computer, that didn't work, I uninstalled and tried to reinstall that didn't work either afterwards every time I tried to install aftter installing, it said "windows is searching for firefox.exe, to locate this file your self click browse" when I clicked where the firefox icon should be.

I did browse and I found firefox's folder, thing is it had no executable file so I uninstalled again, every time I did so it said "an error occured while trying to uninstall mozilla firefox 13.0.1 (d86 en-US) it may have already been uninstalled" which is strange it did not tell me that the first time I tried and after many re-installations. I went through my files and found were mozillas folder was at apparently it did not install or uninstall so I proceeded to delete everything not before I backed up my profile (at least I think I did).

When I got down to the last item in the folder which was another folder it did not want to uninstall the name of that folder was "uninstall" (yes I know inception who what of guessed) turns out the file had corrupted every time I tried to delet it said "An unexpected error is keeping you from deleting the folder. If you continue to recieve this error you can use error code

Sorry I accendently hit post, well to finsih my problem and make it short continue quote, "to search for help for this problem. Error 0x80070091: the directory is not empty"

And it said when I tried to open the folder "the file or directory is corrupted and unreadable" so basically the uninstall function for mozilla file firefox program corrupted and now I can't install or entirely uninstall firefox and it all happened after a routine update.

You can do a disk check with the chkdsk.exe program. If you run the chkdsk.exe program from a cmd.exe Command window then you can read the response from the chkdsk.exe program. Open a cmd.exe window: Start > Run: cmd.exe <press Enter> At the command prompt (>) type or Copy&Paste: chkdsk.exe /f /r <press Enter> (put a space before /f and /r) If you get something like: Would you like to schedule this volume to be checked the next time the system restarts? y/n then answer the question with "Y" and close all programs and reboot the computer.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
