Greasemonkey

[SnoringFrog]

This is one of my favorite Firefox addons. I've been using it pretty much since I started using Firefox, but in the last few months I've begun trying to write more scripts myself. I just finished one up today that toggles the display width for literature pieces on DeviantArt since DA's new layout only gave them half the screen.

Does anybody else use/script for GM? What are some of your favorite scripts?
