arethinn | more firefox weirdness

Also, wtf same version of extension being deemed incompatible with Firefox 1.0 at work and thus disabled, and not deemed so at home and thus left enabled (and working just fine, I might add)? I wasn't downloading nightly builds or anything; these are the same full release packages from the front page of Mozilla. Only thing I can guess is that there's something slightly different about the environment in XP vs 2K.
