4 years ago jspaint includes a meta tag, <meta name="viewport" content="width=device-width, user-scalable=no">
which asks the browser to scale it to real screen pixels, so firefox is likely being correct here.
well i'm not sure if that's what it exactly means, but it's sort of implied.
You can zoom to 200% with your browser's zoom (as a workaround).
It would probably be good to have some condition where it doubles the UI size, but the easiest way of doing that (nonstandard CSS property zoom) breaks some code that does calculations about sizes and locations of things.

Hi. Failed to find a similar issue in the tracker using HiDPI, DPI and Retina keywords, this is what I see in my HiDPI laptop (2x scaled) laptop just in Firefox on Linux but not in Chrome.
I like to see if I can play around it and maybe fix it, where should I look you believe?
Thanks!
