screen shot of memory usage by app, showing Firefox using over 18GB of RAM

I also don't understand why every chat app needs 1GB of RAM to itself.

This site says Linux calls cached RAM "free" but in my screen shot it's definitely being shown as "used". I guess this is a choice of this app?

Most likely, try running htop or top (can't remember which is which) in a terminal.

Well top currently shows:

MiB Mem :  64076.1 total,   2630.3 free,  51614.1 used,  34046.9 buff/cache     
MiB Swap:   4096.0 total,      2.3 free,   4093.7 used.  12462.0 avail Mem 

While the "Mission Center" app shows:

67GB RAM total, 54GB RAM in use. 12GB available. 29GB cached.

Subtract cached and free from total to get actual usage Htop shows visually though with cached as yellow or so I think you are using about 30 gb ram.

Honestly, apart from firefox, what are you running? Does that include vms? I have 8GiB ram(7.1 usable) and uses like 1.8gb on idle and about 5-6.5gb on my personal highest usage

  • Bigotry will not be tolerated.
  • 3. Post Linux-related content
  • Including Unix and BSD.
