Dock — dock

Twenty tabs open. You recognize maybe five. The rest are lost in the strip, their favicons too small to tell apart.

Dock opens as a sidebar and lists every tab, grouped the way you want. Drag a tab from one group to another. Name groups by project, by priority, by whatever makes sense to you. Close an entire group when you're done — twenty tabs become ten, then five, then zero.

Groups live across restarts. Shut down Firefox, come back tomorrow, and your groups are still there, collapsed or expanded exactly as you left them.

No accounts. Nothing sent anywhere. Just tabs, sorted.
