Tabstead: Workspaces and Tab Groups av Fuad Laguda

Keep a workspace for work, one for a project and one for reading. Click a workspace in the sidebar and its tabs come back exactly as you left them, Firefox tab groups and all. The other workspaces' tabs are put away, never closed.

Never lose a tab
- Tabstead hides and shows tabs. It never closes one to switch. The first time, Firefox asks about the hidden tabs: choose Keep Tabs Hidden.
- It keeps a copy of every workspace. When Firefox starts without reopening your last session, Tabstead brings back what is missing, and never opens a tab twice.
- Picking a hidden tab from Firefox's list of all tabs takes you to its workspace.
- A tab you reopen with Ctrl+Shift+T comes back where you can see it.
- When a window closes with hidden tabs in it, the sidebar offers to bring the whole window back.
- One button shows every hidden tab, whatever happens.

Made for Firefox tab groups
- Groups live inside their workspace and stay whole. The tab bar shows only the groups of the workspace you are in, and each one comes back with its name and colour.
- Right-click a tab and choose Move to workspace. A tab in a group takes its whole group along.
- Open any workspace in a window of its own.

Find anything
- Search finds a tab in any workspace and takes you to it.
- Alt+Shift+W opens the sidebar. Alt+Shift+Page Down and Page Up go to the next and previous workspace.

Backups
- A restore point every 30 minutes when something changed, the last 20 kept.
- Save a backup file with the date and time in its name.
- Import a Tabstead or Simple Tab Groups backup. Each group becomes a workspace.
- Restores open tabs unloaded, a few at a time, so 500 tabs restore without slowing Firefox down.

Private
Tabstead collects nothing and sends nothing anywhere. Everything stays in your Firefox profile.
