What is Tree Style Tab?
Tree Style Tab is a Firefox add-on designed to enhance browsing efficiency by managing open tabs in a tree structure. Tabs opened from a parent tab form a child relationship, allowing users to collapse and expand branches, creating a clearer visual history and thematic grouping. It supports customizable trees, drag-and-drop reorganization, and various extensions that enhance its functionality.

This extension provides the ability to work with tabs as "trees".

New tabs opened from the current tab are automatically organized as "children" of the current tab. Such "branches" are easily folded (collapsed) by clicking on the arrow shown in the "parent" tab, so you no longer need to suffer from too many visible tabs. If you want, you can restructure the tree via drag and drop.

  • Such a tree of tabs will behave like a visual browsing history for you.
    • For example, if you see a list of search results for a topic, each search result link will open in new child tab.
    • New tabs opened from these "child" tabs will appear as descendants of their originating tabs.
    • You'll easily dig and dig deeply, without losing your browsing trail - if you want to go back to the original search result, you just have to switch to the "root" tab.
  • Moreover, each tree will reflect a group of tabs on a similar topic.
Please enjoy as you like!
