What it is

OneTab turns open browser tabs into a saved list that users can restore one at a time or all at once. It works with Chrome, Firefox, Edge, Safari, and other browsers, and is listed for macOS and Windows. The maker says reducing open tabs can save up to 95% of memory. Saved tabs can be organized into folders, reordered, merged, or managed with quick lists, search, tasks, and stars. Users can import and export tab lists or share a list as a web page. OneTab is free, with no signup required for tab saving and organization. Its optional Backup & Sync encrypts data on the device before upload and uses end-to-end AES-256 encryption, according to the maker. Sync covers saved tabs and settings, not browsing history or currently open tabs. OneTab remains accessible offline, and changes made offline sync when the user is online again. A single Backup & Sync license covers multiple computers, browsers, and profiles, up to 100.
