lol, i'm honored to be quoted, btw.
basically, on xp go to docs and settings>toe/tanta's documents>app.data>firefox>profiles and create a text document and name it user.js. while you're at it you can remove the word "-example" from the userChrome-example.css and userContent-example.css titles of the files. start up firefox, type "about:config" and you should get a huge of list that you can right click to modify. you should give "about:config" a shot before creating the files if you want to be on the safe side, but i'm not sure it'll work without creating and renaming those things. i'll try to find some links
