Is there a way to keep FF from scaling images when Windows text scaling set to 200%?
I switch between a desktop monitor that is 1080p and a 4k TV on a regular basis and in order for things to be a legible size on the TV Windows scaling needs to be set to 200% or so on that display. Which does make FF more usable on that display. However when viewing images in FF, the images get scaled accordingly as well. IE: A 4k image upscales by whatever amount Windows is set to. In order to view a 4k image at native 1:1 scale, windows scaling needs to be set to 100% which makes everything else unusable.
I've tried searching but can't find a good answer for this.
I'm currently using the ESR release on Windows 10 if that makes a difference. Thank you

Firefox has a text-only zoom setting. To experiment with that, go to:
Settings
In the little search box, type zoom and when the filtered sections appear, check the box for "Zoom text only".
It can be funky, depending on the site layout.
If that doesn't work very well for the sites you visit, perhaps there is another option using an add-on.
There is one more setting worth trying if the text-only zoom does not do it for you. In about:config, set layout.css.devPixelsPerPx to 1.0 and Firefox stops following the Windows scaling, so your images show at their real size. The trade-off I found is that the whole interface gets small on the TV too, which is why I ended up sticking with the zoom text only option jscher2000 suggested, but it is worth a try to see which compromise suits you better.
Zoom Text only was set by default. So playing with that didn't do much. Setting the pixels per px setting to 1 did bypass the win scaling so images scale 1:1 . However it made the rest of the FF UI way too small.. Trying to play with the built in zoom after that helped with website layouts an text size (not this one it seems). But FF UI is still too small.
At least I know what I can do now to temporarily change things to see images at the right scale and switch back I guess. Thanks :)
Okay, so it sounds as though you need the standard upscaling for your regular monitor, but some kind of toggle button for the TV display to "downscale" the images in that page. It should be possible to inject style rules into the page targeting just the images, but I don't have time to play with code for that.
(It seems I have worked on this scaling issue before somewhere, but I can't find it.)
