Have you tried? Firefox won't start - find solutions

Thanks

moderator fixed the hyperlink

hi mate, yep looked at that and hit the link of needs to update before installation can occur.

tried the %data% thing. even used search to find the xpicleanup.dat file.

came up with nothing and it still tries to update a previous version if i try to start it or uninstall it.

cheers

anybody?? im missing my firefox browser bad

Please also try deleting the updates.xml file in the Firefox installation root folder.

hi, did a search on c drive and that file didnt come up sorry

im so frustrated. i just want my firefox back

If present it would be in the Mozilla Firefox folder in Program Files (x86) assuming that Firefox was installed in the default location.

See the Latest Firefox issues article. Try the first suggestion, to download the Firefox installer from mozilla.org/firefox and then reinstall Firefox (see How to install Firefox on Windows for detailed instructions).

For other possible causes and solutions, look through http://kb.mozillazine.org/Browser_will_not_start_up

hi guys/ gals. got it sorted. i had mozilla firefox in c\program files\mozillafirefox so that was ok.

but found this file under the firefox.exe file

firefox.exe.moz-upgrade

deleted it and firefox run updated and im now on 8.0.1 firefox

thanks all for your help

Thanks for reporting that deleting the file firefox.exe.moz-upgrade fixed it. I'll mark your reply as the solution.

This is the first time I saw this file mentioned. A search brought up this previous thread showing the same solution: https://support.mozilla.com/en-US/questions/796566
