Hi dev-platform@, I'd like to unship access to the :-moz-system-metric pseudo-class, and the system metric media queries, from content pages. I just filed <https://bugzilla.mozilla.org/show_bug.cgi?id=1396066> for that.
They're not in any spec, and they seem unused (I can't find anything non-mozilla-related in Github code search). Furthermore they expose system information, which can be a fingerprinting vector, and pretty random stuff like "is a color picker available?". According to Boris it predates Gecko's capacity to not expose stuff. I think it should be pretty safe to unship, but let me know if you don't think that way, or have data that indicates the opposite. The intention is to do that in Firefox 58, given we don't want to add extra risk to Stylo. Thanks! -- Emilio _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
