Firefox plugins & codecs are apparently nonexistent
After a couple weeks after installing Fedora 9, my Firefox 3 plugins & codecs have spontaneously vanished. My themes & Extensions are still there, but I can't do anything that involves opening a file in a browser window. Sometimes it even goes straight to a download window when I click on image files. The first few weeks it was fine (except for flash, which has never worked fully), and now it wont handle any media at all.
What can I do about this besides completely remove & reinstall firefox (and will that even work?)
