I installed Firefox4 and I get an error message everyday about the platform version incompatibility of the XUL, which forces me to re-install firefox everyday.

Since I installed Firefox 4 I keep on getting the error "Platform version 2.0 not supported with...". Is there any way to update the XUL file? I do re-instalations everyday (after the re-instal, firefox runs smooth)

Do a clean (re-)install:

  • Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
  • Don't remove personal data if you uninstall the current version.
  • 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 (not in the Firefox program 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.
