But on the Windows XP task manager(I don't know that process's English name, because I use Windows XP Korean version), there is a firefox.exe process. So I send the Kill signal to that, but after 10 minutes later(Now!!) it doesn't removed in processes list and has 90% CPU resources.

4. Click the X button to restart the firefox.
5. But sometimes it isn't removed. then same problem.
Actual Results:

My OS is Windows XP SP3 and I setup the firefox from 3.5 then update to the 3.6 Korean version.
