    2. This provides tree-style tab bar, like a folder tree of File Explorer . New tabs opened from links (or etc.) are automatically attached to the parent tab.

      Tree Style Tab vs Tabs Outliner opinions
      Most users think Tree Style Tab is a great alternative to Tabs Outliner.
      Tabs Outliner does *two* things: 1) It can act as a session manager; and 2) It provides a more readable, visual UI for sorting & organizing tabs (e.g. indenting/grouping)..... The "Tree Style Tabs" firefox add-on, AFAIK, provides only the *second* feature.... I have yet to see ANY add-on that does both 1) and 2). Therefore, I do consider "Tree Style Tabs" to be an alternative to Tab Outliner -- depending on what feature-set one is wanting.
