/** This script fixes the Tooltips for Netflix' Stars. Netflix wants to have tooltips that 
 ** display useful messages like "Click to rate the movie Hated It," but the tooltips do not 
 ** appear in Firefox at all. This script is a minor variation of ALT Tooltips. See 
 ** http://www.arantius.com/article/arantius/alt+tooltips+for+firefox/
 ** 
 ** This is a greasemonkey script, intended for use with the Firefox extension Greasemonkey.
 ** More info: http://greasemonkey.mozdev.org/
