Right now the title bar just displays duplicate information (e.g. the same text as the current tab), I would prefer to use this screen space for something useful. This change would also make Firefox use less vertical screen space than Safari, instead of more, so that would be a bonus too. Reproducible: Always

Sorry, I overlooked this one. I'll try to be more careful next time. But nice to see it is already planned!
