imho there are some errors in the proposed about:config at
https://anonymous-proxy-servers.net/en/ ... rbird.html

# it's "reply" instead of "replay" in:
mailnews.reply_header_authorwrote %s

# it's "extensions" instead of "extension" in:
extensions.enigmail.mimeHashAlgorithm 5
extensions.enigmail.addHeaders false
extensions.enigmail.agentAdditionalParam --no-emit-version --no-comments --display-charset utf-8
# in the last line it's also "--no-comments" instead of "--no-comment"

Best regards

Thanks, we have done an update of the tutorial.

probably another error in https://anonymous-proxy-servers.net/en/ ... rbird.html

network.cookies.cookiesBehavior
# should be
network.cookie.cookieBehavior

Best regards

Indeed, thanks. I fixed it on trunk.
