How do I have 2 windows, but select which window to open, e.g. a personal window vs. a business window?


When I open Firefox I want to be able to select which window I want to open. Each window will have it's own set of tabs, which can change as I need to. This allows me to open Firefox with either a "personal" window or a "business" window or a "Social media" window etc. How can I do this?
