Did you confirm that this older version is still installed because it is possible that this is only about a leftover (orphaned) uninstall registry key ?

There are still a large number of files in the Mozilla folder.

But is that the same Firefox version as the one you try to uninstall ?

You can check the application.ini file in the installation folder for more detail.

Can I manually delete the program?
