For years, Tor Browser has been one of the most effective tools for protecting privacy and bypassing censorship online. But most people don't experience the internet through a browser anymore.

Snowflake is particularly effective at tackling both of these challenges. It disguises a user's traffic to look like a video call and routes it through volunteer-run proxies using short-lived connections, making the traffic harder to detect and block. That's why i…
