What Tab Manager Plus is
Tab Manager Plus is a free, open-source browser extension for finding, organizing, moving, and switching among open tabs and windows. Its search filters tabs by title and URL while you type, and duplicate tabs are highlighted for management. Users can create, move, close, pin, and unpin tabs and windows. A per-window tab limit can open another tab in a new window after the limit is reached. The extension saves windows for later with session data stored locally in the browser, although tab history is not preserved when windows are saved and restored. The project describes support for Chrome and Firefox and links to both extension stores. Incognito or private-mode support can be enabled in settings. The maker says it does not track extension use or websites, send data to third-party servers, or store settings outside the browser. Tab Manager Plus is licensed under the Mozilla Public License 2.0 and includes tab search, session restore, and tab suspension.
