It looks like the volume really increased at the start of February, then dropped again in the middle of March. Maybe it is a signature change.

I hit this while trying to reproduce another issue under rr.

Maybe this is related to Bug 1683404?

Don't see any crashes on versions more recent than 78esr, and the crash rate is quite low for that (unsupported) version - closing.
