I'm not super techy, but I've read some things on here about rMBPs eating RAM. I've been trying to keep the RAM in check, but the usage is pretty high right now. I don't notice any slow down with my computer, but a lot of RAM is being eaten up according to the Activity Monitor. I have the 8GB model because I really didn't think I would need 16GB on the day to day. Now, I'm regretting it a little. What browser is best for low RAM usage? Here's a screenshot. Any help would be appreciated.
