I've run the Tracksweep Function in the A-Edition. And i've unchecked to delete the History and Cookies.
But now my whole History + Sessions in SessionManager are gone. Tabbed Groups also dissappeared.
Did you also uncheck Tabs? If not, maybe this is why your Tabbed Groups disappeared. I don't like to use programs to cleanup - in most browsers you can select these things to clean manually. Also, I backup my bookmarks and cookies regularly.

Is there any possibility to get that stuff back?
Without backup files, you may need to try System Restore.

Oh, btw: i am using Firefox in the newest version on winXP SP2
Maybe Firefox 3.5 is incompatible? I've heard other problems with the newest FF unrelated to Ad-aware. Firefox 3.5 was released after Ad-aware 8.0.7 - if this caused a problem, Lavasoft will need to update.
