Living Without Adobe Flash If you have Firefox it gives a link for an extension that will default to HTML5. With all the updates to Flash, and the poor performance on mobile devices it seems inevitable to switch. I shared in the comments the extension for Chrome which I use.
Do you know the extension for Chrome? Its called Video5.
Loads HTML 5 video instead of using Flash for supported websites. Uses icons from Glyphish http://glyphish.com/.
