Hello, so like a month ago I've bought MacBook Pro Retina Early 2015 and all this time I've been struggling with one question: what's the best browser for my MacBook? At first I've been using Google Chrome and I loved it, but I've noticed that it's eating a lot of energy so the battery time goes down significantly. Then I switched to Safari, but what I didn't like about it is that Facebook is lagging soooo much on it, I mean sometimes Safari just freezes for like 10 seconds when just scrooling on Facebook. And when I click fullscreen button on youtube video, I have to wait for like 5 seconds for the video to become fullscreen. Now I've installed Firefox, but just when I launched it, my MacBook's fans kicked in - so I guess it's eating a lot of CPU? Any thoughts? I would really appreciate any advice, thanks.
