What makes Firefox hard to dethrone is the fact that every so often a new pretty addon comes up to make it even more beautiful. Now it has another new feature that many would love, especially the ones who like visuals, FoxTab. This addon allows you to cycle through previews of the open tabs you have like the way that Windows Vista and Windows 7's Flip 3D feature allows you to flip through running programs. Now your tabbed browsing can never be prettier with FoxTab. The video above shows this cool new feature.
