Maps is the most frequent offender of something that is "kinda broken" on Firefox - black tiles/boxes, slowness, other things not rendering right. But on Chrome, it works fine 100% of the time.

I have used Firefox on mobile and desktop for a better part of 15 years and I cannot recall seeing black boxes or tiles on Google Maps.

None of that happens for me.
