User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98) Build Identifier: Firefox began this problem after updating to 1.0.4. I love this browser, but when I go to close the browser, the computer seems to hang and the mouse moves very slowly and erratic. I hit CtrlAltDel and Firefox still shows up in the close program window despite having been closed. I then highlight it and end task and when it finally does, computer is returned to normal. Reproducible: Always Steps to Reproduce: 1.Deleted Firefox and reinstalled. 2.Installed and ran Mozilla. 3.Searched bug list Actual Results: After I reinstalled Firefox it continued to have the same problem. I have it on other computers but have no problems. I installed Mozilla and ran it but do not have the same problem when I close the Mozilla window, or IE for that matter. Could not find the bug in the bug list. Expected Results: Firefox should close and there should be no hanging of the computer. Never did it before.

Do you get the same problem if you run Firefox in the Firefox safemode ? http://kb.mozillazine.org/Safe_mode

I tried Firefox Safe mode and the problem continues.
