This doesn't seem to work in Opera v11.11 named as .js or .user.js.
On Win7 32bit with Greasemonkey on Firefox 10

Now is also the popup disabled, F***** GREAT!
Tested with Seamonkey 2.2 and 2.3 and it does what it says. (should be the same in FF5 and FF6)
The direct link on imageshack is available and there are even no annoying pop-ups (saying to register or similar).
