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?

            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

              No VMs. The RAM usage kept climbing until I was crashed out to the login screen and lost everything that was open. It seemed to be a particular website that gobbled RAM.

              The RAM use kept growing until it locked up and I got booted back to the login screen, losing everything unsaved. Now it’s back to normal but when I run free -m the numbers match what’s in the GUI.

              I’m pretty sure the culprit was a website for uploading photos for printing. Something odd about it, I did upload 1,000 photos at about 2GB total, but it was sucking up RAM Like crazy. Firefox was using some fifty-something GB of RAM.
