Too many tabs open. Everyone has this problem. The mental overhead of planning to come back to things later turns into 40 open tabs slowing down the browser.

The real problem is not tabs. It is the lack of a save-and-return workflow.

What Tab Manager and Session Saver does

Saves your current open tabs as a named session. One click. When you want them back, restore the session with one click. Each session has a name you give it — project research, reading list, work context.

Sessions persist across browser restarts. Close Firefox, reopen, your sessions are still there.

Why browser history does not solve this

History is chronological. It does not group all the tabs from a research session as a unit. Finding the right 8 URLs from three days ago is a manual hunt.

Named sessions solve the grouping problem. The tabs stay together because you saved them together.

No backend needed

Sessions are stored locally in Firefox extension storage. Fast to save, instant to restore, nothing to sign up for. No sync means no server to trust with your browsing context.
