    • Two shoutouts for excellent writeup - Nice job Sunil!

    • Comments on Jira ticket from MT - please review and address

      • One thing I’d like to see considered, in addition to the enterprise policy that switched to a PNA mode for a given network, is the ability of the local network to opt in to that sort of treatment.

      • The mixed content arrangements here might need work. I’m OK with us not allowing passive mixed content unless enterprise policy explicitly admits it (or there is some user-accessible setting; please ensure that this setting is available, at least in about:config).
