By default, Tor Browser protects your security by encrypting your browsing data.
You can further increase your security by choosing to disable certain web features that can be used to compromise your security and anonymity.
You can do this by increasing Tor Browser's Security Level.
SECURITY LEVELS
Increasing the Security Level in the Tor Browser Security settings will disable or partially disable certain browser features to protect against possible attacks.
This in turn might stop some web pages from functioning properly, so you should weigh your security needs against the degree of usability you require.
You can undo the changes at any time by adjusting your Security Level and restarting the browser.
Standard
- At this level, all Tor Browser and website features are enabled.
- Tor Browser, by default, is set to the "Standard" Security Level.

This may cause some sites to lose functionality.
- JavaScript is disabled on all non-HTTPS sites.
- Some fonts and math symbols are disabled.
