Even though the specific signature is new to me, FireFox has become crashing quite regularly during YouTube playback in the latest versions of the browser (starting with the version 54 or even maybe 53).
Andrew, do you recall seeing other crashes like this? It looks like there's a couple different root causes mixed up in the SegmentedVector signatures, though...

I see a few that look like the longstanding DeferredFinalizer crash.
