so when i explore the world and attack mobs, for the most part i watch my url change to the attack page, but it doesn't get a chance to load (only makes the page go white) before it is redirected to an error page saying i am trying to attack too soon.  I have killed the mob, but it's kind of obnoxious that I can never see the attack.  I don't have any add-ons on firefox or any other programs that might be previewing the page, and once in a while i can see the attack, but it's only like 1/10 that i get to see it.  

Are you using a Web Accelerator? The fact it only applies to npcs implies that it's a precache.

However, there are times when Firefox picks up two clicks when you have only pressed it once.
I will convert the attack link to a button and route the data through POST instead of GET. That will stop Firefox getting ahead of itself - a**uming it conforms to HTTP specifications

no i don't use a web accelerator.  as for the other stuff, i have absolutely no idea what you just said, but sounds good
