Overview
OneTab is a straightforward and efficient browser extension that addresses the common problem of tab overload. With a single click, it converts all your open tabs into a list, dramatically reducing memory usage and decluttering your browser window. The extension focuses on simplicity and privacy, with no unnecessary features or data collection.
