if possible.


== Discussion ==


https://www.reddit.com/r/TOR/comments/kj7git/is_bamsoftwarecom_related_to_the_tor_project_in/

    Malwarebytes apparently blocks snowflake.bamsoftware.com and
snowflake-broker.bamsoftware.com.

    But this should not have happened since
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/31250
(webext-0.0.6), which changed *.bamsoftware.com to *.freehaven.net?
https://gitweb.torproject.org/pluggable-transports/snowflake.git/commit/?id=bd43c345db0ef139bc2e598433d0c5f7af4d843a

    How did this user get a copy of the browser extension that still
contacts these old domains?
