Remove Quicktime Plug-in 7.7.8; Refreshing did not help.

more options

Advised to remove Quicktime Plug-in 7.7.8 (which Firefox had deactivated). The Add-on Manager does not have a "remove" option. Found Mozilla advice to refresh Firefox. After doing so, Quicktime Plug-in 7.7.8 is still installed and now appears to be active. How can I remove it?
