the “qa contact reclamation” announced in this post is scheduled to go live this wednesday during our july 4th outage:
bugzilla.mozilla.org will be unavailable for 2 hours on Wednesday, July 4th from 8-10pm US/Pacific (3-5am, July 5th UTC)
tl;dr: the “qa contact” field for bugs will now hold the person responsible for the qa of that bug, use “component watching” to watch components.
