Hi, In bug 1523712 I intend to unship the `-moz-binding` CSS property from content pages.
This property is used to attach an XBL binding to an element, and it's pretty much useless already in content because we don't allow to attach XBL bindings to most elements already if not coming from a chrome stylesheet: https://searchfox.org/mozilla-central/rev/78cd247b5d7a08832f87d786541d3e2204842e8e/dom/xbl/nsXBLService.cpp#855 This effectively removes the property from the OM and makes @supports (-moz-binding: url(foo)) start evaluating to false / not parsing. Let me know if there's any concern with this, but with privileged in-content XBL already gone, it seems worth trying to do this sooner rather than later. It is behind a pref (layout.css.moz-binding.content.enabled) just in case, and because we still need it for tests. Let me know if there's any concern with this. -- Emilio _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
