This is a spin off of https://webcompat.com/issues/5910 The test case is <div> <select> <option value="001">001</option> <option value="002">002</option> </select> </div> with select { -webkit-appearance: inherit; } in Gecko, it shows a -moz-menulist widget, aka it resolves to -webkit-appearance: auto; in WebKit and Blink, it shows nothing, aka it resolves to -webkit-appearance: none by default. -webkit-appearance: auto resolves by default to a menulist widget (on Desktop on WebKit, Blink and Gecko)

Created a test case here https://codepen.io/webcompat/pen/YVwXda (I haven't tested yet on real mobile devices).

Hmm, so this means '-webkit-appearance' in Chrome and the css-ui spec for 'appearance' aren't reconcilable. https://drafts.csswg.org/css-ui-4/#appearance-switching We should probably change the spec to say 'none' is the initial value, and then add 'appearance:auto' in all rules in our UA sheets that have a -moz-appearance declaration.

Sounds about right. Please raise the relevant spec issues...

Thanks for the kind offer, but I already have patches that seems to work: https://treeherder.mozilla.org/#/jobs?repo=try&revision=786ce80b6fa26eacb9718b37c7f185b17479e6aa

BTW, I found some XUL files with <hbox style="-moz-appearance:listbox"> and whatnot, which doesn't work without also specifying 'appearance:auto' now that 'none' is the initial value. I'm worried that XUL add-ons might do something similar, so I suspect we need to also add a rule in xul.css to specify 'appearance:auto' as the default for all generic XUL elements.

Safari and Edge have the same results as Chrome for the testcase. Filed a spec issue: https://github.com/w3c/csswg-drafts/issues/1250

Comment on attachment 8860099 [details] [diff] [review] part 1 - [css-ui] Make 'none' the initial value for 'appearance' for web and UA compatibility. Add 'appearance:auto' to UA sheets for form controls, XUL etc where needed. I don't think you need the xul.css change. We always apply minimal-xul.css to documents. r=me with that bit removed.

This broke TB twist lists on Mac only, see bug 1358840. We're looking into whether this can be fixed in C-C.

The 'appearance: auto' in minimal-xul.css doesn't seem to have any effect on treechildren elements, so treechildren::-moz-tree-twisty and so on have lost their native styling.

Sorry about that. I guess the problem is that the universal selector * doesn't apply to pseudo-elements (sigh). I guess we have to make an exhaustive list of XUL pseudos too. Unless we have some internal non-standard ::-moz-any-pseudo or something...

Adding dev-doc-needed - we probably ought to mention this somewhere in the docs.

I have added a note about this to the appearance browser compat data: https://developer.mozilla.org/en-US/docs/Web/CSS/appearance#Browser_compatibility The "Initial value" info at the top of the page still says "auto", but I've submitted a PR to change this in our data repo: https://github.com/mdn/data/pull/83 I have also added a note the Fx55 rel notes: https://developer.mozilla.org/en-US/Firefox/Releases/55#CSS Let me know if this looks OK, or if anything else is needed. Thanks!

Chris, support for unprefixed "appearance" got backed out; see bug 1365614. You should probably talk to Mats about what the documentation should actually say here, but I believe at this point no engine ships the "appearance" property that's in the spec, nor has any plans to. The prefixed "-whatever-appearance" properties have totally different behavior from the spec property, and shipping the spec property in the form it's in right now is almost certainly not web-compatible...

OK, thanks Boris. I'll contact Mats offline and follow up on this; at this point I am confused as to what I really need to write.

The issue on Firefox Nightly 55.0a1 (2017-05-24) (Desktop and Android) for https://webcompat.com/issues/5910 aka https://rumble.com/register.php?src=https%3A//rumble.com/ is not solved. The reason is the site contains only -webkit-appearance: inherit; which is ignored for us, and the same for: * -webkit-appearance: none; (ignored on Gecko) * appearance: inherit; (ignored on Gecko) The only way to fix it on their site for now is either to use -moz-appearance: inherit (which resolves to none) like in WebKit/Blink world. -moz-appearance: none appearance: none is not working because of Bug 1365614 being backed out.

Should we reopen this one?
This was backed out in bug 1365614 (along with other bugs).
