Ok I installed it using the commands for Ubuntu. So it was a .deb package

I’ve only installed browsers with commands from their official website and I’ve also installed flatpaks.

I’m not sure if stock Firefox on Zorin is a flatpak or snap but it has no problem rendering the CSS.

Is Waterfox a good alternative?

I hated that question when I worked at jobs where I got yelled at by customers.
