I tried high grade beta and firefox 13 14 and only get the error message, only to return to 10.2 works

I had used with 12 Firefox problems. and upgraded to 13.0. Error message is

"Platform error 13.0 version is not compatible with minVersion > 13 message appears." (The same with beta 14)

Nor, 12, 13 or 14 will work only by removing everything and 10.2 installation allows me to use Firefox. Uninstallation of 12, 13 or 14 and relocation do not work, error is always present and firefox is not running.

Do a cleaning (re) install and delete the folder of the program Firefox (C:\Program Files\Mozilla Firefox\).

Download a new copy of Firefox and save the file to the desktop.

Uninstall your current version of Firefox, if possible.

  • Do NOT remove the data personal when you uninstall your current version of Firefox, because all profile files will be deleted and you will also lose your personal data such as bookmarks and passwords from other versions of Firefox profiles.

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

Your bookmarks and other profile data stored in the Firefox profile folder and will not be affected by a relocation, but make sure that you do not select delete data of a personal nature if you uninstall Firefox.
