Security Levels
1
Standard
All features enabled. Most usable but least secure. Good for everyday browsing where anonymity is main concern.
2
Safer
JavaScript disabled on non-HTTPS sites. Some fonts and math symbols disabled. Better security/usability balance.
3
Safest
JavaScript fully disabled. Many features disabled. Maximum security for high-risk users.
Best Practices
Do
- Keep Tor Browser updated
- Use HTTPS versions of sites
- Use "New Identity" when switching tasks
- Close browser when done
- Consider using bridges in censored regions
Don't
Don't install plugins
They can break anonymity and leak identity
Don't maximize window
Window size is a fingerprinting vector
Don't torrent over Tor
BitTorrent leaks your real IP
Don't log into personal accounts
Links your Tor session to real identity
Don't open downloaded files while online
Documents can phone home
Using Bridges
Bridges are unlisted Tor relays that help bypass censorship. Use them if Tor is blocked in your country.
- Request bridges at bridges.torproject.org
- Use obfs4 bridges for best obfuscation
- Enter in Tor Browser settings > Connection
