Tree Style Tab

This innovative Firefox extension introduces logical tab organization through parent-child relationships. When you open a link from a tab, it automatically becomes a child tab indented beneath its parent. This creates a clear visual history of your browsing flow, helping you track your research paths or project workflows. You maintain full control—easily rearrange tabs via drag-and-drop, collapse branches you're not using, and quickly navigate related tabs. It's the smarter way to browse multiple related pages simultaneously.
