Firefox sometimes crashes when I'm on kbin.social: happens to anyone else?

As title suggested.

Has happened to me at least 5-6 times, every time it happens I am logged on to kbin.social and have some other tabs opened at the same time... So I am strongly suspicious that kbin has something to do with it, but I could be wrong.

I've almost never seen Firefox crashing on my OS before. Not sure if it is a bug of some sort.
