I also use ff-esr on an old machine with 4GB RAM. It starts with 2
processes, one uses ~300MB (RES) and one ~150MB. It doubles in size quite
quickly after some browsing (especially something like Facebook or
Linkedin). When watching YT videos it grows to ~1GB. The SIZE column is
~1.5GB here. Note that the only add-on I use is uBlock Origin.
Although I think these sizes have become quite ridiculous, I never saw
memory usage that big. But I have to say I usually close FF if memory
usage gets out of hand.

but he has no means to realize it other than through violence.
