I've had this problem for some time now; just decided to ask about it. I have a Imac running Sirra version 10.12. I have 10 gig of memory. I use Google Chrome as my browser. There is a weather site (The weather Network) that I use to keep track of the weather in my location. Problem is; if I leave the page open at this weather site for any long period of time; it gobbles up all my memory. Just a few minuets ago I checked my computer and my memory program showed that I had only 23 mb of memory left. This is common for this site. Just wondering if someone knows what could be causing this and what I can do; other than not use this site anymore.
