Tab Set Keeper

Save the tabs in your current window as a named set, then restore that setup whenever you need it. Tab Set Keeper remembers each tab's URL, order, pinned state, and active state. When you open a saved set, matching tabs already in the current window are reused and only missing tabs are created. Tabs outside the set are kept safely at the end of the window instead of being closed. Key features: - Save the current window as a named tab set - Preserve tab order, pinned tabs, and the active tab - Overwrite an existing set by saving with the same name - Reuse matching open tabs and create only missing tabs - Rename, duplicate, and delete saved sets - Remove selected tabs from a saved set - Store all saved data locally in your browser - English and Japanese interface No account is required. Tab Set Keeper does not use analytics, advertising, tracking, or external servers.
