There is also Ladybird browser that IIRC already has a more complete web standards implementation than Servo despite being a much younger project. Though it’s still far from being ready and performance is really bad. But so far it seems that it’s going to outpace Servo.

For me in Plasma 6.3.2 it has noticably different font rendering compared to 100% scale with increased font size. Text looks thinner than it normally should. It’s probably the consequence of downscaling.

Too bad fractional scaling is still not universally supported. In Firefox it’s buggy and disabled by default (and pretty much abandoned), and using default compat mode (when app is rendered at nearest greater integer factor and then downscaled by compositor) has some strange font rendering issues and potentially worse performance (on 4K monitor the resolution Firefox would be rendering itself would be humongous).

Thankfully in my case I can just increase font size and it works much better than with fractional scaling.

This for whatever doesn’t work on openSUSE Tumbleweed, last time I checked.

IIRC this extension just doesn’t work in Flatpak. You need to use Firefox outside of the sandbox, installed via package manager or official build from Mozilla.

Are you saying that not all bourgeois are the same?
