I have Windows Vista on my system and Mozilla Firefox 4 is my default web browser, previously I was using Mozilla Firefox 3.6.15 I had the same problem with that version too, and I upgraded to Firefox 4.0 and yet I am facing same problem. My problem is have some Java console programs (6.2.20 6.2.21 6.2.22) in Add-ons and I am not able to clear up or remove those programs From Add-ons I think I have to reinstall the firefox, is there any other solution to this problem. Please help,
