Tab View di Chris Lutz

Tab View brings back the beloved tab grouping experience that power users have missed since Firefox removed Tab Groups.

Features:

Create named, color-coded tab groups to keep work, research, and browsing separate
Visual grid of tab thumbnails so you can see everything at a glance
Switch between groups instantly — tabs outside the active group are hidden, not closed
Drag and drop tabs between groups
Search across all your tabs by title or URL
Keyboard shortcuts to cycle through groups (Ctrl+Shift+. / Ctrl+Shift+,)
Right-click any tab to send it to a group
Save and restore backups of your groups and tabs
Light, dark, and system themes
Available in English, German, Spanish, and French
All data stays in your browser — nothing is collected or transmitted.
