Can't drag tab on Firefox 12 with torbutton 1.4.5.1 enabled

It seems that I can not drag and drop tab (switch or detach) on Firefox 12 with TORbutton 1.4.5.1 enabled.

... with torbutton enabled but whatever tor is activated or not ! (that's major)

Confirmed in both 1.4.5.1 with Firefox 12 on GNU/Linux and after building Git master. (and it's not easy to figure out that the problem comes from the Tor Button extension)
