Problems with FF 8.0 and Panorama Rated 4 out of 5 stars

With FF 8.0 on windows 7 SP1 (64b) and Tree Style Tab V.0.12.2011110101. I have 102 tabs in 3 groups (Panorama) and 1 windows. If I go in "Group your Tabs" (Panorama) and change tabs to another from one group, I can't exit "Group your Tabs". I have to kill Firefox Process. In FF 7.01 everything is ok
