FF 57 was much snappier on my Mac than on Chrome, but it occasionally turned into a CPU hog and got the fans spinning full blast. Did anyone else experience that?
Most of the time when it happens on Reddit it stops if I turn on uBlock Origin and refresh the page. Sometimes, though, it still happens even after that.
Why do you turn it off in the first place?
Unless it turns out that the high CPU usage is the fault of the ads (which I've not been able to prove), Reddit's ad system is the kind of ad system we should be encouraging, so I don't block them.
FF57 spiked my cpu to 100% most of the time and Netflix was really laggy. I went back to Chrome because it only uses 10-20% CPU with regular usage.
In FF57, I was using default performance and browser settings.
I see no reason why CPU activity should spike to 20% every few seconds with one blank tab open and no extensions enabled.
Is it possible to whitelist cookies per domain in Safari?
Closing the tab reduced the cpu usage to normal levels.
