There are two more strings similar to the one in page context menu:
Открыть в новой мультилогинной вкладке (in bookmark context menu)
Открыть текущий адрес в мультилогинной вкладке (in mouse gesture)
Do we need to change them from мультилогинной to мультилогин?

in these context menus and in mouse gestures, according to the rules, it will be correct to be мультилогинной, but I would change it to мультилогин everywhere so that there are no different words in different places
Because the question is “where to open?”, and the answer is “открыть в мультилогинной вкладке”
but in menu (where there are three dots), the question “open what?” here the correct answer is “открыть мультилогинную вкладку”
the difference is in the endings, but if you write a мультилогин, then in this particular case, without endings will suit the meaning and rules
