Snowflake
Snowflake is a pluggable transport from the Tor Project. If you have an uncensored connection, running this extension volunteers your connection to be used as a Snowflake proxy to help users unable to connect to the Tor network. Your IP will not be visible to the sites users visit using your proxy, as this extension will not make you an exit node. Note, this add-on does not work with WebRTC disabled.
If your access to the Tor network is blocked, this extension will not assist you, and you should use the Tor Browser instead.
