According to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent/Firefox#windows, natively running ARM64 Firefox does not send its architecture identifier in the User Agent string.

Accorgint to my own test just now, it actually identifies itself as x64.

This doesn't seem right, as this means that there is no difference between the UA strings sent by actual x86(-64) platforms and ones running ARM64. I believe it would make sense to replace x64 with something else on ARM64 platforms.

:mossop, do you know what component this should live in, or who might be the best person to triage this?

The user agent is part of networking, however according to bug 1763310 this appears to be intentional so it may be the case that this is a docs bug.
