Nearly two days ago Mozilla released the 11th version of Firefox. Yesterday I saw that the new version have landed on Arch repository. Today it have landed on Ubuntu. Now, you can simply update your systems and you’ll get the latest version of Firefox.
This new browser comes with add-on sync and support for more HTML 5 and CSS 3 standards. It have some big updates for web developers. It also contains some critical security fixes. So, you should update as soon as possible!
