The Tor Project released an addon for Firefox and Chrome so that one can easily run snowflake proxies. You can find their links in this page: snowflake (dot) torproject (dot) org
Snowflake if you don’t know is a WebRTC pluggable transport for Tor.
By the way what is the current status on Snowflake support in Whonix? Is there anything more recent than github (dot) com/Whonix/anon-connection-wizard/pull/22 ?
