I love that Firefox exists and Quantum is an amazing step forward, but Firefox still regularly runs away with gigabytes of RAM and hung worker processes. I have no problem with long-lived Chrome sessions but I need to restart Firefox ~daily. It's not bad memories of 10-years ago.

I've been using Firefox as my daily browser at work, home, and on my mobile devices, and I've literally never had issues with Firefox taking up too much RAM. Chrome on the other hand was always one of the main culprits when my computer(s) would start to slow down.

This is the problem with anecdotal evidence; everybody's subjective experiences are slightly different and further colored with their own biases, so you can never get hard facts out of it.

And yet Chrome consuming huge amounts of RAM is an actual meme

Same for me.

I've been using FF for a couple of months and I get huge random CPU spikes on my MBP that go away once I restart it. It works fine on my iMac and Windows tower though albeit JS execution seems slower (I mostly work on front end stuff).

It also seems to consume more battery on Android than Chrome although I admit I've never made any serious testing.
