Firefox refusing to open new tabs

[DarkShadow]

On any forums I visit, when I try to right click and "Open link in new tab" It just refuses to work.

Yes, I'v checked all options and re-installed tabbrowser prefferances, but still no luck

Can anyone please help me?

Nevermind, seem a fresh install of backup and extentions sorted it.

Thanks anyways
