Just another data point: (Might be related, might not...)

I'm seeing something similar with 4.19.1, though it doesn't completely
crash it just casues all GUI operations (even just switching windows) to
become *really* sluggish until I reboot the machine. At that point
firefox gets so slow that it's basically unusable -- this might be
experienced as it having hung on a slower machine. I am able to quit it
with regular Ctrl+Q though.

Downgrading to 4.18.19 seems to fix it for me.
