1673132 - Remove -moz-default-appearance values "scrollbar" and "scrollbar-small"

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, task)

Description

[Markus Stange [:mstange]]

These values are only used on macOS. They can be replaced with scrollbar-horizontal and scrollbar-vertical, and scrollbar-width: thin.

Bug 1205643 did this conversion for other platforms but not for macOS.

Other platforms were already converted to scrollbar-horizontal and scrollbar-vertical in bug 1205643.

Depends on D94673

I've added a rel note about this: https://wiki.developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/84#CSS

I don't think anything else is needed. We don't seem to mention -moz-default-appearance anywhere on MDN.

I think https://developer.mozilla.org/en-US/docs/Web/CSS/appearance still mentions -moz-default-appearance

It was also used in the XBL implementations of the widgets that ship with the Mozilla platform. Starting with Gecko/Firefox 80, these uses were changed to -moz-default-appearance, which should never be used outside of internal stylesheets.

Good to know, but the removed values aren't mentioned on that page, so nothing needs to be done.
