OneTab proves to be an invaluable tab management solution available as a browser extension for Chrome, Microsoft Edge, and Firefox users. This tool efficiently addresses the issue of cluttered tabs, enabling users to swiftly organize their browsing experience. Once activated, OneTab closes all open tabs within the current window, preserving them as a consolidated group for future access. The outcome is not only a tidier interface but also a remarkable reduction of up to 95% in memory consumption, ultimately leading to enhanced browser performance.
