If using Zone Alarm's browser virtualization or any other similar product or a sand-boxing program (i.e., Sandboxie), turn it off when updating Firefox or Firefox Add-ons. You can post on the forum for any such product that you might be using to get other instructions on the proper use of the product.

The updater wasn't able to update all the files and some were left as older versions. Do a clean reinstall. See: Browser will not start up - XUL Runner error after an update

  1. Download a fresh Firefox copy and save the file to the desktop.
  2. Uninstall your current Firefox version.
  3. Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
  4. Install the fresh copy of Firefox that you downloaded in step 1
