Tab Session Saver de olivia

Tab Session Saver helps you keep your browser organized by saving all open tabs from the current window as a named session. You can restore the full session later, rename saved sessions, remove old ones, and search through saved tab titles or URLs.

The add-on also includes JSON export and import, so users can keep a backup of their sessions or move them between Firefox installations. An optional setting can close saved tabs after saving, which is useful for cleaning up a busy browser window.

All session information is stored locally in Firefox. The add-on does not use analytics, external servers, advertising, or tracking.
