Now that the number input implementation is stable, we should consider enabling the pseudo elements for content. A good place to start : bug 930010

The reason that they're disabled is because Simon Sapin thought we might be able to do things a better way, perhaps using Web Components. Since Web Components aren't complete enough to play with for this use case yet it's hard to know if that will work or not.

I don’t know if Web Components are the right approach or not, but was there any discussions of this in a standards body? Please consider https://wiki.mozilla.org/WebAPI/ExposureGuidelines before exposing new features to the Web.

Is there a spec for this? Should we make one?

I don't know of a spec for this, but it seems like if we want to expose them to content, there ought to be a spec. (Do other browsers implement them?)

This'd be a great feature since native buttons look terribly on "transform:scale(3);", at least on Win7

Is Firefox the only major browser that doesn't support `::-webkit-inner-spin-button` today?

(Do other browsers implement them?) Webkit and Blink support the pseudo-class mentioned above as well as ::-webkit-outer-spin-button[1] and ::-webkit-textfield-decoration-container, respectively. As far as I know, only CSS UI 4 specifies[3] some styling for form elements, but explicitly doesn't define any input specific styling like special pseudo-elements.

> only supported by Chrome, Opera, and Safari Ah, but I just checked and IE / Edge don't support spinner controls (arrows) at all, so that means FF is the only major browser that a) has spinners and b) doesn't let you style them explicitly. Combine that with bug 1158435 and you have number field controls that are worse than nothing for some users. I've seen other feature requests kept open because Firefox wants parity with the competition. Does that apply here?

Does that apply here? I'm not a Mozilla employee, so I can't speak for them, though I guess this bug is kept open simply because of the need for styling this form field, not necessarily to catch up with other browsers.
