I tried putting this line but it doesn't work:
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js
jQuery doesn't work in Greasemonkey at all. Is there other way to use jQuery in Greasemonkey?
For all the people who have the same problem, you must upload the file to greasespot then install it from there.
The Create New Script option wouldn't work!
