Hi, I would say because it was launched around 2wks ago and that Google does not share proprietary information with it's rivals for browser share and for revenue.

I imagine it will be able to use it once Mozilla Developers work with it.

That's part of answer. However, if the Titan key leverages FIDO U2F, and we enable U2F in Firefox Quantum, then what is the technical reason. I spoke with the developers and PMs fir Titan, and they do not care about share the of U2F key market, and they specifically built the Titan key to the specification.

@ahusmc, did you not read the reply. FF isn't the creator nor has that information to update that since it just came out.
