Mozilla launches Firefox 4 beta 4, rolls in Sync, Panorama tab manager
Mozilla Tuesday updated Firefox 4 to its fourth beta release, adding two major new features: Firefox Sync and Panorama.
Firefox Sync lets users access browser history, password keychain, bookmarks, and open tabs across their different desktop computers, iOS, or Maemo-based mobile devices. Sync is available as an add-in for Firefox 3.5 and 3.6, but in Firefox 4, it is a built-in feature.
Firefox Panorama was formerly known as Tab Candy, and it debuted in alpha several months ago to critical acclaim. To solve the problem of too many browser tabs being open at once, and turning into a cluttered mess; the feature lets the user arrange their tabs into groups. The result is similar to HTC and Samsung's Android UI layers that let the user zoom out and see all the homescreens at once.
Mozilla's Aza Raskin Tuesday said, "While there are many directions still left to explore...there is a strong set of design principles that have and will continue to guide development. We've already seen activity from extension authors to extend the capabilities of Panorama, which makes now a perfect time to discuss Panorama's design principles."
