Firefox Panorama

- formerly known as group tabs, TabCandy


Why is it that you can remember where the knives are in your kitchen, which has hundreds of things, but have difficulty remember where a particular tab is? TabCandy is a project that helps users deal with the complex ways the modern web is used by providing spatial, touchable groups of tabs and tab groups.

The Pitch

Current Status

  • Working now on integration with trunk. See 574217.

Downloads and Code

Problem Space

  • Tabs don’t scale.
  • It’s time consuming to switch between tabs.
  • We work in semantic groups; our browser don’t.
  • Our tabs have no understanding of search. Only basic understanding of “apps”.
  • Bookmarks are to heavy, tabs are too light. No metaphors for saving/sharing/viewing what we are seeing.
  • No incentive to clean up.
  • We spend 76% of time on first & last tab.

Goals / Use Cases

  • Make switching between tabs easier
  • Make grouping, saving, and managing tabs easier
  • Productivity when you increase monitor size goes up by ~30% (recognition+spatial memory), bring this efficiency gain and ease of mind to tabs.


  • Whole-sale replacement of tabs (by default)
  • Slowing down tab switching (with gratuitous animations, etc)
  • Being an alt-tab replacement
