Bugzilla

TODO in more commits:
1. SUMO link
2. transitional text for Fx80 (attachment 9163538 [details])
3. [.properties references in security/](https://searchfox.org/mozilla-central/search?q=master+password&path=.properties&case=false&regexp=false)

:Keeler, do you happen to know if we use security/manager/pki/resources/content/changepassword.js in Firefox? If not, do you know if other applications use it?  It seems like Firefox uses toolkit/mozapps/preferences/changemp.js instead.

:Pike, is it fine to keep the [two C++ references using .properties file after this change](https://searchfox.org/mozilla-central/search?q=CertPassPrompt&path=&case=false&regexp=false) since there aren't any other consumers of Fluent from C++ yet and we want this in Fx80?
