I just made some changes to fix this issue, so please let me know if you guys are still having a problem. Thanks for the feedback.
Oooops, I use FF3 on Linux and with ABP - I have 120+ tabs open and no crashes ... I guess I can TRUST Linux then... (but been using Linux since 1992)
After a month or so of not having any problems, I'm starting to get them again when ads.elitetrader tries to load. Firefox becomes non responsive for a while and sometimes a forced quit is required.
