It works, but I can't use it as the one thing I don't like about it is it replaces slashes with %2F and corrupts the address for any social site to use. Please remove this aspect and simply use addresses as-is so we don't have to manually fix them every time. I'll use this addon if you do so.

(UPDATE: Apparently this is a site by site issue. I just found out that sites like comicsands do this while others don't. Not sure why.)
