We are well beyond the point of a majority of common hardware having built-in kernel drivers and userland software for extra stuff like RGB control that the best advice is rather avoiding Linux, to instead avoid the trash hardware (NVidia for the time being, GoXLR, Broadcom, etc.). My GPU, audio hardware, network interfaces are both popular products and have worked out of the box for years now.

A summary from its site and known technical details:
As for Windows 7, nobody should really need to install Librewolf anyway on such a device. No device running Windows 7 should have access to the internet at this point. If you are asking about compatibility intending this use case, you have bigger problems to worry about than your choice of browser. If you just need to view HTML files graphically, even Internet Explorer or an older firefox ESR will do.
