Feature Request: Allow「Enable vertical tab mode sidebar for some windows individually」

Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below: - One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case. It brings much more convenience, at least for situations just like mine :)
