I am using a Dell laptop, Windows 7 is my OS. Been running with Mozilla Firefox for a year now, no problems. The only thing that changed is I installed Trend Micro Titanium. I was using it as a free promo the prior year and had no issues- it was ready to expire so I installed a purchased copy. Lately when I try deleting an e-mail from my Yahoo acct, Mozilla gets hung up, gives me a non responsive status in status bar, sometimes it gets past it, but lately I get a "Script stopped running" message, asks me if I want to stop the script or continue running the script. I select stop script but the error message keeps popping up with new script errors. I eventually have to do a ctrl/alt/delete to get it to shut down. The only other thing I have open is Facebook. Please help me, I have exhausted everything I could do at my end. I went on Mozilla's help page and did the link to fix crash errors. Seemed to work for a few log in episodes, but now is back to acting up.
