When I installed Zone Alarm Free it also installed an AddOn in Firefox 8.01, this is disabled because of incompatibility. All greyed out no buttons to do anything.

I try to uninstall Zone Alarm and then checked Firefox and the AddOn was gone, but when I reinstalled Zone Alarm It came back again, completely disabled and no buttons.

During the installation I made sure to deselect all the check marks for the various toolbars.

I need a way to uninstall Zone Alarm Security Engine Add-on, manually if necessary by using the registry.
