Tree Style Tab is a Firefox WebExtensions add-on that displays browser tabs in a vertical sidebar as a tree, automatically nesting tabs opened from other tabs. It supports collapsing branches, drag-and-drop restructuring, and exposes an API for other add-ons.
Use cases
- show firefox tabs vertically in a sidebar
- organize tabs as a tree based on how they were opened
- collapse groups of related tabs to reduce clutter
- restructure tab hierarchy with drag and drop
- keep a visual browsing history while researching
- extend tab behavior from other firefox addons via its API
When to choose
- you use Firefox and open many tabs that you want grouped hierarchically
- you prefer a vertical tab bar in the sidebar
- you want mature, actively maintained tab-tree functionality
When to avoid
- you use Chrome, Edge, or another non-Firefox browser
- you only need simple vertical tabs without tree nesting
- you need a signed stable build for very old Firefox versions that are no longer supported
