Hello I have problem with latest Firefox 7.0.1 (before that never happen with early versions). So the problem is after 20-30 mins using Firefox - mozcrt19.dll start's to use cpu 50% (100% for one core) and during that time pages can't load at all. Then I restart FireFox and all is working fine again. I reinstalled FireFox but still same problem.

I deleted all folders/files in C:\Program Files\Mozilla Firefox\extensions\ so for now no more hangs.

Possibly rather drastic action. I guess that indicates that it is one of your ex extensions that was involved in the problem.

One bit of good news for those suffering from hangs is that after some recent problems I understand firefox developers are trying to now prioritise changes required to provide automated reporting of firefox hangs. (Bug 429592 - catch process hangs )

For general info on hangs
