removing google toolbar from firefox

first, try removing through the add-ons menu, and try add/remove programs in control panel, if that doesn't work:

1. close firefox
2. do a search for 3112ca9c-de6d-4884-a869-9855de68056c
3. make sure you have checked to search for hidden files
4. destroy all instances for this folder
5. restart firefox and it should be gone
