Instead of using htop, could you show your results with smem? Run
`smem -k` for human-friendly units. To see specifically gnome-shell or
firefox:

 smem -P gnome-shell$ -k
 smem -P firefox$ -k

Look at the USS and PSS values.... USS is, roughly, memory which
wouldn't be used if just that process weren't running. PSS divides
shared memory among processes using it.

FWIW, on my F23 system right now, up for six days, I get this for gnome-shell:

  PID User     Command                         Swap      USS      PSS      RSS 
 1947 mattdm   /usr/bin/gnome-shell               0   164.1M   177.4M   219.8M
