I know how to remove addons, but 'Open with Photoshop' is not removing itself: I installed version 1.2 of 'Open with Photoshop', then i updated firefox, but the addon didn't work. There have been many updates for both firefox and 'Open with Photoshop' since then, but I can't upgrade or remove the addon to install the latest version and use it. how should i do this? I have ended up with version 1.2 that wont remove, and version 2.2 floating between the list of installed and uninst6alled addons in the addons manager. Help please?!!! It won't uninstall on nightly 13 (04/03/12) and firefox 10.0.2
