Your firefox blocking script is also blocking Camino and Safari. You might want to fix that, as neither of those support the plug-in you are so angry about and therefore unnecessarily block readers. Also, it's not hard to filter for ad blockers if you're crafty. That might help you avoid false positives. Google for it :).

Good luck...

I tried to block them, they made a work around. I rewrote it to get around their work around, and they made another work around. So I blocked FireFox, which also blocks any browser using the Mozilla engine. Now I'm getting daily hate mail from FireFox zealots who apparently think Mozilla is a religion and anyone who doesn't use it is a heretic and an infidel. IE, Netscape or Opera are easy enough to use so I doubt I'll ever lift the Mozilla block, even if they stop endorsing theft.
