It’s all fun and games till they check for web USB support. They don’t need to actually use web USB but it’s a telltale sign that you’re not on Chrome.

A plugin could very easily have Firefox claim to support WebUSB, but return no devices or junk devices. Some of the anti-fingerprinting add-ons already do, iirc.

You get my point though, all they need to do is start supporting a feature that’s not easy to spoof.
The real defense against this is for people to refuse to use Chrome. It’s not the tail that wags the dog, Make The Firefox user base so big the developers can’t ignore it. Basically IE all over again
