Tor Browser's HTTPS-Only mode automatically switches thousands of sites from unencrypted "HTTP" to more private "HTTPS".
Can anonymity in Tor be compromised?
Tor is the most widely used system in the world for anonymously accessing Internet. However, Tor is known to be vulnerable to end-to-end traffic correlation attacks when an adversary is able to monitor traffic at both communication endpoints.
Do you need HTTPS on Tor?
Use HTTPS websites
Tor encrypts your traffic to and within the Tor network, but not from the exit node to the final destination site. While Tor Browser uses HTTPS Everywhere to force encryption, not all sites support it. You should still keep an eye on the URL bar to ensure the websites you visit are safe.
