If you open a new windows in Nyxt browser, you’ll notice that it will have the exact same tabs as the old window.
Same can be done with Emacs when in server mode: frames (windows) do share the same set of buffers.
I think this is a comfy feature, since windows’ purpose is - IME - not to logically group tabs but rather only to give multi pane visualization when browsing.
So the question is: Is it possible to achieve this in Firefox?

That’s not really what I meant. Having two different views of the same page is indeed awesome but troublesome given the way JavaScript works.
What’s neat for me is the fact that I can select any tab in either window. I often get ~50 tabs in Firefox and sometimes I need to open a new window: what I get is a window with 49 tabs and a window with 1 tab: having to manually move them is a chore. It would be cool instead to have 2 windows with the same set of 50 tabs.
