Merge All Windows: Zero Permissions

Merge the tabs of every window into the current one in one click. No permissions, nothing reloads, nothing collected.

Gather the tabs of all your browser windows into one, with a single click. Click the toolbar icon: the tabs of every other normal window are moved to the end of the current window, and the emptied windows close by themselves. Nothing reloads. Tabs are moved, not closed and reopened, so pages keep running: forms in progress, scroll position, video playback and Back/Forward history are all kept. Private (incognito) windows and normal windows are never mixed. Zero permissions. The extension declares no permission and no host access, so the browser shows no warning at install time. It only handles tab and window identifiers, and never reads the URL, title or content of any tab. - No data is collected, stored or sent. The extension makes no network request. - No analytics, no telemetry, no remote code, no third-party service. Known limits: tabs that belong to a tab group may lose their group when they change window. If the move is interrupted (for example while you drag a tab), click the icon again to resume with the remaining windows. Works on Chrome and Edge.
