Hi please search for Windows Task Manager on your System then Find Firefox and Click then End Task.

DO not use cleaners to do anything with Firefox as it will delete your Profile as well as Program Files.

If you need to boot into Safe Mode and install or add/remove https://support.eset.com/kb2268/?locale=en_US&viewlocale=en_US

Never delete this as it is your bookmarks and passwords.

Try using a full version installer
