Keep sessions short

Tor Browser sessions accumulate state over time. Cookies (locally), history, cached DOM state. None of this is inherently dangerous, but a long-lived session is a longer window for anything to go wrong (extension update, JavaScript on an unrelated tab misbehaving, cross-origin exposure).

The Bureau's recommendation: close Tor Browser after each Nexus session. Open it fresh when you need it again. Use New Identity between different market accounts and between browsing Nexus and browsing anything else.

This is a small habit, mostly invisible to your workflow if you already close the browser when you finish. Worth reinforcing.
