Yes, I simply couldn't use it because it drained my macbook battery too quickly. I just updated to 58, but it seems to still be a problem.

Same here - first thing I did when v58 came out was check to see if CPU usage was lowered, which it unfortunately wasn't.

I see no reason why CPU activity should spike to 20% every few seconds with one blank tab open and no extensions enabled.

To save battery life I'm trying to switch to Safari (from Chrome -> Firefox) but container tabs in Firefox are amazing - the ability to automatically open a domain in a container is perfect.

Is it possible to whitelist cookies per domain in Safari?
