Simple Tab Manager nga Danny

Simple Tab Manager brings order to open tabs from one small toolbar popup.

Choose Organize all tabs to bring matching windows together, remove exact URL duplicates, and sort pinned and unpinned tabs separately by domain. Each tool can also be run on its own.

By default, pinned tabs stay pinned and tab groups stay together; both can be turned off in Settings. A pinned URL copy always wins over an unpinned copy. Query strings and fragments remain significant, and Firefox container identities stay separate. Loading and missing-URL tabs are protected from duplicate removal. Split-view tabs are left untouched.

Open-tab URLs are processed only inside Firefox when you choose an action. The extension has no analytics, accounts, advertising, remote code, or network requests. It never sends or stores tab URLs or titles.
