I know at least 2 cases where the recording-window-ended notification is annoyingly not fired when I think it should: - when the user clicks "Stop sharing" in the UI. (This is blocking me from making reasonable UI changes in bug 1050802). - when an iframe is navigated away (very likely the cause of bug 1049810). Looking at the media manager code reveals that both these cases go through the MediaManager::OnNavigation code path.

Try was green (except for an unrelated Windows failure from https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=d25aeae7a346): https://tbpl.mozilla.org/?tree=Try&rev=40d248b42dac https://hg.mozilla.org/integration/mozilla-inbound/rev/daa75e9e4f30

We need to uplift this if we want to uplift bug 1050802.

Comment on attachment 8475993 [details] [diff] [review] Patch Approval Request Comment [Feature/regressing bug #]: webrtc urlbar indicator. I don't think it's a regression. [User impact if declined]: direct user impact: navigating away of an iframe using getUserMedia will keep a stale sharing icon in the URL bar. indirect user impact: uplifting this patch is required if we uplift bug 1050802. [Describe test coverage new/current, TBPL]: covered by a test. [Risks and why]: low risk, but we should uplift bug 1058650 (regression fix follow-up) at the same time. [String/UUID change made/needed]: none.
