How to get rid of old extensions and add-ons

How can I remove add-ons and extensions? Or, how can I check compatibility ? I've read the FAQ's, they are useless. There are no "remove" buttons. There are no "check compatibility" buttons. Firefox just updated to 7.0 and now my add-ons are disabled, and I would like to uninstall them and delete them from my computer if they are of no use anymore.

Extensions that do not have a "Remove" button are installed by other software and are not under control of the Firefox extension manager.
Extensions installed that way need to be removed via the settings (preferences) in the program that added the extension to Firefox.

Thank you for the reply. Sounds like the extension manager needs to be re-written if it can't manage extensions. I would think the extension manager would at least tell me what/where the application that installed it was. I have some Java Development Toolkit plugin that says it is a script library for use with "deploy". I can't find any Java Development Toolkit on my computer, so I guess I'll just leave it disabled until the firefox people can fix their broken extension manager.

Thanks for taking the time to try and help me though cor-el.
