I too had problems as mentioned by the 1st post Petr Venzhofer ( 4 Dec, 2011). The tabs in firefox got blocked, and everything, like dialogboxes and tabs didnot display. I had to start mozilla in safe mode ( shift + double click on mozilla thunderbird exe file ) and then disable this addon. After that, it resumed to normal condition.
