When replying to a thread on the WoW class boards, if I use button 3 on my mouse to open the board in a new tab(or even if I single click just to go back to the board) via the link over the post box, it opens a Wowhead redirect rather than opening the class board in a new tab(or just going to the board) as I had intended.
If it matters, Firefox 3.6.13.
