I have a lot more crap and tabs open than at work as well as more Photoshop CC usage and 8GB has never been an issue. I'd suggest you investigate what is going on with your machine because it's not normal to require more than 8GB of RAM just for browsing the web.
FF with 10 tabs open all day is only using just over 0.5GB. It might go up to 750MB if I'm doing a lot of opening/closing of new tabs, using Firebug etc a lot.
