Moving Firefox windows between screens with different text size settings

On my Surface Pro, I have the Surface screen display Scale ("size of text, apps and other items") set to 200% as it's resolution is 2736 x 1824. I have set my second screen scaling to 100% - resolution is 920 x 1080. When I move opened apps between them, they auto-adjust - e.g. Excel, Word, Signal, WhatsApp, Zoom, Mozart music processor, MS Paint, even Microsoft Edge (not that I use that browser too often). Basically, any app I use .. apart from Firefox.

Firefox retains the 200% from the main screen so shows itself huge on the 2nd screen when moved there.

Why (indeed, how!) does Firefox do this? What setting, if there is one, can I use to correct this "naughty" behaviour?

Understandably, it's hard to take a screenshot and "prove" this behaviour happens. While creating this post, all of this window down to "naughty behaviour" shows on the Surface Pro screen. But if I drag the Firefox window over to the 2nd screen the "When I move..." line is the last fully showing line of text.

Oops .. slight typo . Second screen is 1920 x 1080. Somehow I missed seeing I'd omitted the "1" off the start of the first number!
