I like the idea of putting Facebook related pages in a container. Why Firefox does not automatically open a new tab/window for this container so that only Facebook would loose track of my browsing history? How I can adjust Firefox to always open containers in a new tab/window and leave the original page intact on its tab? I can — If I would always remeber — open the Facebook related container on a new tab. Why this could not happen autiomatically, or happen based on my container settings? it seems all I can adjust is the colour of the bar above the tab. I other words: What is the advantage of me too loosing connection to my browsing history? Yes, there is a workaround: I can open the container in a new tab if i recall to do so — and yes — I can open "history" and find the page leading to "facebook" from there, but would it not be so much easier, if I could have it done automatically?
