I like to have more than one window open, for different things, depending what i'm doing. however, since I started using Multi-Account Containers, it's been trying auto-combine windows when I first open something. So, maybe I'm doing some research on new gear, and open a window exclusively for Amazon, so I can buy/wish list what I'm finding. I can open a new window, but as soon as I go to Amazon.com, Firefox tries to combine that tab into the existing window. This is happening independent of which containers are being used. How can I make the auto-combine stop?
