What it does
Cookie AutoDelete is a browser extension for deleting unused cookies after tabs close, with allowlist, greylist and manual-cleaning options.
Cookie AutoDelete makes cookie retention a deliberate choice. Add a site to the whitelist to keep its cookies indefinitely, or to the greylist to retain them only until the browser restarts. Then enable Automatic Cleaning; the README presents that as a separate step. Deleting cookies can sign you out or reset preferences, so preserve only the sessions that need it. Configuration export/import carries the policy to another supported installation. This manages cookies rather than every way a website identifies a visitor.
