Cannot open Firefox. Platform error version 1.9.2.15 is not compatible with minVersion > = 1.9.2.16 maxVersion < = 1.9.2.16

Received an update yesterday that disabled Norton before installing itself. Now cannot open Firefox. Get the error message.

This problem can occur if the update was not able to update all the files.

Do a clean install (re)-:

  • Uninstall your current version of Firefox and remove the Firefox program folder before installing this copy of the Firefox installer.
  • Do not erase personal data if you uninstall the current version.
  • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.

Your bookmarks and other profile data is stored elsewhere (not in the Firefox program 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.
