Let's try the following:

  • Restart your Computer
  • Uninstall Firefox from your Control Panel (Make sure to leave your personal information)
  • Go to Computer, then C:/ then to Program Files (It may be called Program Files (x86).
  • Find the Mozilla Firefox folder, delete it (or rename it)
  • Open another browser Window, go to www.getfirefox.com.
  • Download and install Firefox

Does this fix your problem?
