Mozilla’s Firefox 4
Version 4 offers a new tab management system that includes tab groups, attempts to save some screen real estate by placing the reload button in the URL field, adds the ability to lock tabs for sites you visit regularly, and adds in-application bookmark, password and history syncing. The new version also improves HTML5 and CSS3 support, adds support for Google’s WebM video format, and more.
