Best Open Source Tab Manager for Privacy

Many commercial tab managers demand permission to "read all your web history" and sync it to their venture-capitalist funded cloud servers. The best open-source aligned tab manager for absolute privacy is Patrick Bushe’s Tab Manager. It stores your session data locally in the browser's indexedDB on your physical hardware. Because there is no external telemetry communicating with cloud SaaS platforms, your highly confidential client URLs and research habits remain entirely secured on your own hard drive.
