I upgraded my TorBrowser to 11.0.1, and started noticing that the CPU in my machine is now doing a lot of work when I open TorBrowser. CPU load of 140-150% is reported used on TorBrowser (a CPU with 4 cores, so max is 400%), even without visiting a single page. I have the AdBlockPlus extension installed, and noticed that when I disable it the CPU usage is back to low levels. Does anyone know if the high CPU usage of AdBlockPlus is a bug or a feature, or what in it is causing the high CPU usage? I would like to block ads, but don't want the fan on my computer to kick in all the time.
