In general, we can't improve the situation by adding more functionality. That's just physics. The API will necessarily degrade fingerprinting for every sensor we decide to support. Let's say that we add the ability to get access to a humidity sensor. Even making it possible to learn that the capability exists will allow sites to divide users into two groups: those with a humidity sensor and those with out. I'm not saying that we shouldn't make these capabilities available. There can be reasons that outweigh the costs (for instance, I think that we generally agree that VR is a use case that justifies some increase in fingerprinting exposure), but we should consider each capability individually and provide justification and mitigations. If we can find that justification and adequate mitigations, we might then conclude that this is a net gain for the people who trust us enough to install Firefox. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
