I'm having problems with QuickTime content. My add-ons list contains two versions -- QuickTime 7.2 and QuickTime 7.7.1. Even when I click Never Activate on the older version (which can't be updated, since it is blocked) QuickTime doesn't work. I can't find any way to delete the older version of the add-on. Is there any way to do that? Or do I have to delete Firefox (along with all my saved bookmarks) and start again?

No joy. Tried everything. Re-initialized the plugins- database. Manually removed the Quicktime files. They're still there. And if I click Never Activate on one QuickTime plug-in it does the same to the other.

You can see the file path of all plugins, whether enabled or disabled, on the about:plugins page.
