Oh, it just looks like the curve is rasterized before ui scaling, and most of the rest of the UI isn't.

Are you restarting Firefox each time before these screenshots? We're (at this time) not flushing the SVG cache on system theme / scaling changes.

These aren't SVGs...

Oh, you're right. I forgot, the stroke is an image. :/

We don't support dpx greater than 1 on Linux at the moment. Bug 946987 made it so we downscale the @2x images on Windows when the dpx is greater than 1. Bug 995733 is the long-term solution to make the tabs scale better but it needs some more platform support.
