Firefox 47
Firefox 47 has been released. This version enables the VP9 video codec for
users with fast machines, plays embedded YouTube videos with HTML5 video if
Flash is not installed, and more. There is a blog
post about these and other improvements. "Now, we are making it
even easier to access synced tabs directly in your desktop Firefox
browser. If you’re logged into your Firefox Account, you will see all open
tabs from your smartphone or other computers within the sidebar. In the
sidebar you can also search for specific tabs quickly and easily."
See the release
notes for more information.
