That’d require a lot of work from me – at this point it would be easier for me just to switch to Vivaldi, or hardcode my fixes as patches into Firefox itself.
In fact, the per-screen HiDPI setting even has an environment variable on most Linux systems (Qt’s QT_SCALE_FACTORS), but Firefox completely ignores that.
I don’t have the time anymore to rewrite half the UI stack of every single application I use, and then take over maintenance of that. I’ve done that with a few open source projects, but my time is limited. And if I wanted to implement extending the UI properly, I’d definitely have to rewrite the entire stack, similar to what Browser.html does.
