Would really be great to move windows or tab groups between different profiles; Edge offers this. Sometimes you don't realize what profile you're in and you start doing stuff in your personal profile that doesn't fit there. With firefox right now there is no way to select and move any tabs, tab groups or windows to the profile that is best suited for those links.

It could be a privacy risk, though, because by directly moving a URL (and all its parameters) to another profile, it might be easy to link them together on the server side. It’s not necessarily a problem, but it’s definitely important to be aware of, since one of the main uses of profiles is precisely isolation for privacy and security.

Not even drag and drop to the window with a different profile?
