Firefox - JavaScript help.Follow

Alright, well, I downloaded IE Service Pack 2, and it messed with my explorer's settings, so now I have no 'Create new tab' button, which I can't live without. So I went to Firefox, and googled some ways to make FF faster (having abandoned IE). Fast forward about an hour, I go to WoWhead (looking for the mats for my goggles) and it says Wowhead won't work without Javascript...

Thing is, Javascript is enabled in my FF options.


How can I resolve this?

Long story short, I re-open Firefox, and go to Wowhead, where it says JavaScript is needed, and I go to see if it's already on, and it is.

I am posting this from IE, since FF isn't letting me click post >.<
