recently can't do much of anything cause firefox is using greater than 80% of my memory, why? I switched to firefox from chrome but it seems firefox tends to use much more memory....disappointed as I like the functionality

Desktop or Laptop? I've been using this site for a long time. https://www.crucial.com/store/systemscanner#hero Just run the scan and it will show you upgrade options. Then you can compare prices on eBay. I wonder what's the ram usage when you first login without opening anything...

If you're on a laptop, I just bought 4 sticks of the same speed as yours on eBay at a great price. see screenshot

In your original image, Firefox is only using about 17%. Your Desktop Window Manager is way out of whack. That should be around 30-60 MB. Do this with windows and apps closed. Right-click on Desktop Window Manager and select End Task. In the dialog that opens check "Abandon unsaved data and shut down"', then click Shut Down. Your desktop will disappear and restart.
