I knew from years ago that you could have multiple profiles in Firefox, and since Chrome is really choking handling games like Farmville 2 lately (not sure why, but Firefox is Zynga's recommended browser anyway), I decided to set up profiles and profile shortcuts. But there's a BIG problem. With Chrome, when I set up shortcuts to profiles, which Chrome lets you do with one click, by the way, if I have one profile already open, I can open windows in all the separate profiles just by using their shortcuts. In Firefox, I cannot. If I have one profile open, the other shortcuts merely open windows in the same profile already open. This is not acceptable. It's not like the profiles are in the same directory. They're in separate directories and there should be no issue opening two or more profiles at the same time.
