This script works fine in Firefox, but it replaces the "Print address label" button, so you can't print out a "You've got a game from Goozex!" slip without disabling it.
Doesn't work at all in Google Chrome.
I love this script and use it for both Goozex and Bookmooch. It's a real timesaver.
The features it has work great so far as I can tell.
the other reviewer should be ignored.
