Firefox works on Wayland now. So, unless you have redefined Firefox as a non-major browser, "is far from certain whether any of the major browsers will ever run on Wayland" is flatly wrong. Also: https://github.com/01org/ozone-wayland

And the obvious point is that turning ChromeOS into a full linux distribution defeats the point of ChromeOS itself: to have very few "moving parts", and only those necessary to launch Chrome. Also, the bulk of the work "for wayland" is not wayland itself: it is KMS/Mesa/glamor/libinput, which are already used by ChromeOS (except for libinput, I think).

Can I run Firefox on Wayland without X, i.e., without XWayland or some other compatibility layer which includes most of X's source code files?

If so, do you know where I can download it?

Just because that is why Google created ChromeOS does not mean that those of us uninterested in Google's vision cannot bend it or parts of it to other purposes. It is after all distributed under open-source licenses.
