I am currently using MacOS, and I have the latest version as well as the latest version of Firefox, but I seem to keep having this issue where the menu bar disappears like on the picture below. This happens when I am using my two displays. I am watching a video on my external display (on full screen) as I am browsing the internet on my Macbook Pro display. For some reason the program disables the menu bar on the Macbook screen (where I am browsing). I never had this type of issue with another browser and don't want to switch back just because of this minor issue. I would really appreciate if somebody can refer me back to something, I have tried searching but no luck. Thank you! Image here --> https://imgur.com/a/ZnZ3btw
