Maybe, this seems to only happen after several crash(bug 1133306) and restart browser.
Too many firefox.exe process remains in Task Manager.

Comment 2

[Paul Adenot (:padenot)]

This can be caused by the audio mixer process being confused by all the crashes and not accepting all connections.

Comment 3

[Lawrence Mandel [:lmandel] (use needinfo)]

Tracking 37+ as the description in comment 0 reads like a regular enough use case.

Paul - Comment 2 makes it sound like you have an idea of where this bug may come from. Can you take this one to investigate?

Comment 4

[Paul Adenot (:padenot)]

Yep, that's one of the things I'm looking at at the moment.

Comment 5

[Paul Adenot (:padenot)]

bug 1134258 and bug 1134263 are going to make this happen way less. In _extreme_ cases, and depending on the hardware, this will still happen, though, and there is not a lot of thing we will be able to do.

Now that bug 1133190 is fixed, does it still occur?
