Did you check this action in Options/Preferences -> General -> Applications ?

You can also check handlers.json in the profile folder and open this file in a Firefox tab. Be cautious with editing this file if you aren't familiar with data in JSON format.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.


You can inspect the MIME database key with the registry editor (regedit.exe) and do a search for that MIME type (file extension) via Ctrl+F. Be cautious with editing the registry as there is NO UNDO possible: all changes are applied immediately. You can export key(s) in the registry editor before making changes.

You can check specific file extension keys (e.g. .rar) in the registry with the registry editor.

  • HKEY_CLASSES_ROOT\.xxx

You can check a possibly linked MIME type in the MIME Database registry key.

  • HKEY_CLASSES_ROOT\MIME\Database\Content Type\

Do you get a valid (working) RAR file if you change the file extension of the saved file to .rar ?

If that is the case then it is likely a problem with the Windows registry.
