Merge all windows

This is a browser extension for Microsoft Edge and Google Chrome. When you click the button, it merges tabs in all windows into a single window. Yep, it's that simple. It essentially provides the same feature as the Merge All Windows feature in Safari. This is handy if you open many websites in many windows and you want to consolidate your workspaces. Unlike existing extensions, this one requires no special permissions and does not require your browser history.
