Rated 4 out of 5 stars

Well since nobody's rated this puppy - ever! - I thought I'd put my 2 cents in. Of course I cant speak from experience since I'm running Firefox 3.0.5 [sad face]. I really like the idea though. I've been using Mr. Tech so long it seems fun to change the icons up a bit. Refreshing. Alas, I have no idea if it's advised to override version compatibility and force install this anyway... But seeing how the last update was in 2006, I'd rather not take the gamble without an express go-ahead from Mr. Tech himself OR someone equally knowledgeable. Anyone listening out there???
