Safari is going crazy, sucking-up memory and CPU like there's no tomorrow. Doesn't seem to matter what other apps I'm running. It works fin for a few minutes then goes nuts. Battery life is barely an hour. Chrome and Firefox both work fine. Anyone else having these kind of issues? 2011 MBA, MacOS 10.12.2 EDIT: I dragged ~/Library/Safari folder into the trash and reopened Safari. Maybe that will work.
