This is the largest list I have seen yet of GreaseMonkey UserScripts, GreaseMonkeyUserScripts – An Unnamed MoinMoin Wiki.

I have looked through the whole list and have found many that are very helpful for my browsing experience. To name a few of the UserScripts that I have installed:

• Anti-Disabler: restore context menus on sites that try to disable them, created by Dive Into Mark.
• Inline MP3 Player: Inserts an inline play button(flash plugin required) after every link on page that ends with a .mp3 extension, created by Hideout.
• TextareaResize: allows you to make textareas larger using the keyboard, created by Julien Couvreur.
