What is snowflake?
From the Tor website:
Snowflake is a system to defeat internet censorship. People who are censored can use Snowflake to access the internet. Their connection goes through Snowflake proxies, which are run by volunteers.
If your internet access is not censored, you should consider installing the Snowflake extension to help users in censored networks. There is no need to worry about which websites people are accessing through your proxy. Their visible browsing IP address will match their Tor exit node, not yours.
If you consider this important or relevant, consider either toggling the slider below and keep this page open (you’ll need to enable cookies), or installing the snowflake extension for Chrome or Firefox.
