We might be off-guard in some aspects with respect to automation. Lots of stuff that's currently working for Firefox/Fennec in beta might break for mozilla-release. This is a tracking bug to remember what we've done, if any.
Moving this to track just Firefox for now. Will file a separate bug for Fennec.
Created attachment 8856819 [details] [review] use mozilla-unified for docker image tasks Since these keep dying on hg clone.
I think we are done for now. We've successfully shipped 53.0. If anything else comes up, will reopen and add further along. Assigning this to :aki as he's done the heavylifting both in this bug and bug 1318919.
