Load Flash Video as HTML5 Automatically with FlashToHTML5 Safari Extension
FlashToHTML5 is a great Safari extension that will attempt to load all YouTube Flash videos as HTML5 at the highest possible resolution, helping you to maintain a Flash-free Mac OS X installation and thus giving portable Macs more battery life by reducing CPU usage.
The extension serves the same purpose as the manual HTML5 experimental setting in YouTubes preferences, but if you don’t have a YouTube login then you can’t force HTML5 video anyway.
If you do have to use Flash for other reasons, it’s highly recommended to install a ClickToFlash plugin for Safari or enabling the included click-to-load Flash feature in Chrome, both offer the same benefits that prevent CPU hogging Flash video from automatically loading in the browser.
Nice find this morning from 9to5mac.
