Hi ahelena-

I do not know precisely why you are getting this error. I would suggest doing a full uninstall, and then installing the latest version.

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

  • It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

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.

I hope that helps!

I am having this problem as well. It started after a virus infected the system. The virus has been removed. I followed the directions above and they did not solve the problem.
