Hi, you might have noticed that Can I Use provides a little Resources tab with links to Mozilla's bug tracking system, "Bugzilla".

The bug for this has a low priority of P5, which basically means "nice to have". It's unlikely to be taken up by employees, but code could be submitted by an external contributor. Even then, there appear to be a number of privacy issues discussed in the bug that may hold up release.

Hello Firefox team, I would like to know when Firefox browser start supporting the Client-Hints header to collect user agent info using following headers: Sec-CH-UA, Sec-CH-UA-Arch, Sec-CH-UA-Bitness, Sec-CH-UA-Platform As this is already supported by other browsers like Chrome and Edge wanted to know from Firefox as well. https://github.com/WICG/ua-client-hints#explainer-reducing-user-agent-granularity

HI, Thank you for your reply. I think that but is not relevant to my ask. Sorry original url I shared was taking somewhere else. I was actually looking into Sec-CH-UA-Arch, Sec-CH-UA-Bitness, Sec-CH-UA-Platform to detect architecture, platform and bitness values of the endpoint.

Yes., these:

• https://developer.mozilla.org/docs/Web/HTTP/Headers/Sec-CH-UA-Arch
• https://developer.mozilla.org/docs/Web/HTTP/Headers/Sec-CH-UA-Bitness
• https://developer.mozilla.org/docs/Web/HTTP/Headers/Sec-CH-UA-Platform

The answer is the same: low priority for Mozilla. For planning purposes, assume "not this year."
