That was my first intuition, too. There is even a classic website about this  
very topic: https://www.linuxatemyram.com/

HOWEVER, given that the OP mentions looking at the RSS sizes I think the  
classic "all memory used" issue is already ruled-out. The issue seems to be  
modern webbrowsers which could be considered OSes on their own already hence  
they also claim more resources whenever it is useful for them.

Firefox takes just above 1600 MiB here with only six tabs open for four  
hours. Yet I am pretty sure it would take less were this a "lower-end"  
system e.g. fewer CPU cores would cause fewer processes to be spawned and  
hence the memory efficiency might be better in such cases.
