Tree Style Tab: Organize Firefox Tabs in Trees

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.

Add-on summary

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!

Tips:

  • "F1" key toggles the TST sidebar.
  • "Tree Style Tab" toolbar button also toggles the sidebar. If it's unnecessary, you can remove it from the toolbar.

Прекрасное дополнение!!! Без него мне не комфортно работать в браузере Firefox. Благодарен автору!

Cannot uninstall this extension. I removed it through Firefox and it does not show up in extensions, but it is still there in context menus and in functionality. I don't know how to remove it now. It's occupying the top of my context menus when I right click, but there is nothing to uninstall.
