This is a GreaseMonkey script that changes the plain blue thumbs on StumbleUpon blog pages to the nice green and red thumbs used in the toolbar. It has only been tested on Windows XP with Firefox 22.214.171.124 & GreaseMonkey 0.6.4 but should work with any Mozilla/GreaseMonkey configuration.
To install this script, right click here and select "Install User Script."
