HTTPtoHTTPS von Marre

This is the story behind the add-on:
Because of certain restrictions I could not use Facebook outside HTTPS. Ok, fine, no problem. But whenever someone posts a link and I click on it, Facebook does its redirect thingy which always uses HTTP. So every time I have to manually type in https:// just so I can view the original link. Well, NO MORE! I said, and so this add-on was born. Hope somebody finds it useful also.
