I recently did some research on why the retina MacBook Pro models seem to heat up considerably when simply browsing the Internet. I found that most of the overheating and poor battery life issues stem from poor Flash performance and the necessity of Safari, as Chrome and Firefox destroy MacBook performance. So I installed YouTube5 in order to play YouTube and other Flash videos as HTML5. I even uninstalled Flash, as this is the only way to make sure that no websites are running Flash ads and still draining battery/causing overheating. I thought this was an acceptable fix until I noticed a lot of websites won't work using YouTube5 (Gamespot, Giantbomb, TheVerge). I also noticed that this only allows YouTube videos to be played at a max resolution of 720p and many other websites that will run using YouTube5, run at very poor resolutions that are nearly unwatchable on retina resolutions. So I've started to realize that the YouTube5 plugin is far from perfect, but the Flash alternative still seems like a pretty poor option as well. So I've come here to ask you guys how you deal with the terrible Flash performance on your rMBPs or MBPs in general. Are there any other plugins I could try? I can't imagine everyone here just runs Flash and puts up with 50% of the advertised battery life and burnt legs.
