I'm running on a dual Xeon with hyperthreading enabled (4 logical CPUs) so sometimes Mozilla gets 25% (90% of the cases) and sometimes 50% of the total CPU usage. Even when this happens I can work and the application is stable, but in order to free the CPU I need to restart it. Reproducible: Sometimes Steps to Reproduce: Expected Results: Normal CPU usage.
please try without multizilla
I uninstalled MultiZilla yesterday and this morning the mozilla process was getting 25% of the CPU again so Multizilla is not to blame.
Is there a way on Windows to get a thread dump of the Mozilla process so that one can see which thread is getting all of that CPU time?
does the CPU usage continue if you close everything except 1 window, open a new window and then close the 1 window that you left open? Also please try a clean profile (mozilla -profilemanager)
I had already tried that (closing all windows, then opening a new window and then closing the previously opened window) and the CPU usage stays high. I'll try with a new profile later today and see if it helps.
