privacy.resistFingerprinting.letterboxing enables letterboxing like the torbrowser uses and privacy.resistFingerprinting.letterboxing.dimensions allows to set a custom size.
The trade-off is lost screen space and an uncommon user experience.
The alternatives could be a browser addon that lies about the screen size at least in javascript (css media queries probably only work with letterboxing), but I currently can't find one.
