So I set up about 20 Palemoons on a computer running 40 browsers. The other 20 are Firefox.
It ran almost all day yesterday, and today the PC restarted about 30 minutes ago, and it's all good.
Here is how task manager looks, for comparison if anyone cares:
Firefox version 55.0.2
Palemoon version 28.9.0.2

Clearly doing significantly better on the memory. Maybe a little better on the CPU.
All the browsers are doing the exact same stuff. I mean, not all the exact same stuff at the same time, but, the same sport and the same game. Like not every player on the field is doing the exact same stuff as the next player, but they're all playing the same sport and the same game on the same field at the same time
So there. All looking good so far. I'm liking Palemoon.
