Today Mozilla updates Firefox 4 to Beta 4 version bringing two interesting features: Panorama and Sync.
With Panorama you can easily drag and drop your tabs into manageable groups that you can organize, name and arrange in a fun and visual way. So you can keep track of all your open tabs. This is a new conpet to browsers and Mozilla is the first to implement it. By clicking on the top right button you will be able to acess Panorma area and in an easy way create tab-groups, resize groups, moving tabs from one group to other etc.
With Firefox Sync you can swich to one computer to other, from Firefox mobile to computer and hold the same data on the browser. Sync gives you seamless access to your important Firefox data – including bookmarks, passwords, history and open tabs – across multiple computers and devices.
