Status: RESOLVED WORKSFORME

Description

[Daniel Holbert [:dholbert]]

This bug was filed from the Socorro interface and is 
report bp-9419677f-3b21-4182-bcb0-1e1fa2170215.
=============================================================
In my Firefox Nightly browsing session right now: every time I visit https://open.spotify.com/browse/featured (which I'm logged in to) and try to play some music, I get a dropdown notification saying "The WidevineCdm plugin has crashed", and no music plays.

Here are 3 sample crash  reports:
bp-4f9bdcce-b6f5-4261-98f7-f9ca42170215
bp-9419677f-3b21-4182-bcb0-1e1fa2170215
bp-ebaf4dfc-0d63-4fb2-9411-38a8a2170215

I think this happened to me at some point last week, too. IIRC, a browser restart makes the problem go away. So, we're likely getting ourselves into a broken state that we can't recover from.

Is this issue still reproducible?

I haven't hit it in recent history (and I do visit the Spotify URL from my STR a few times a week).

So, I think it's WFM.
