A long time ago I extracted a file to Firefox that changed Danbooru's background from white to gray. Since it isn't a regular add-on/extension/greasemonkey script, I can't remember what or where it is. Unfortunately, it makes Danbooru 2 look horrendous, I can't find it on Google, and the Danbooru forum search is inop. I've looked through both appdata and the Program Files folders for anything obvious but didn't see it.
Does anyone happen to remember what/where it is? I can't stand using the site with white bars all over the place.
