Mozilla is testing a new Firefox interface designed to tame that seemingly endless string of tabs stretching across the top of your browser and beyond. Mozilla Creative Lead Aza Raskin has released Tab Candy, an experimental feature for Firefox that reimagines tabbed browsing through tab groups and reorganization.
Tab Candy is designed to make it easy for you to go through all the open tabs through a visual experience. It looks highly inspired by the Mac OS X Expose and Spaces feature. With one key press, Firefox would show an overview of all tabs. You would be able to check them all and pick the one you want to maximize.
Tab Candy is not an extension, but a new feature that Raskin and team plan to build into a future version of the Firefox browser. In essence, it creates a desktop-like workspace for users to separate and organize open tabs into groups. When opened, these groups act like their own instance of the browser.
