Comment(by mikeperry):

 Technically, this actually breaks NoScript's ClearClick protections, but I
 have not noticed NoScript ever successfully blockeding a real clickjack
 with ClearClick.. And I have been clickjacked..

 If I'm wrong, and ClearClick actually does block real clickjack vectors in
 a normal Firefox, perhaps this ticket should be bumped to major or higher.
 It could be that other TBB changes also break ClearClick..
