As of Firefox 154, I intend to turn the sibling-index() <https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Values/sibling-index> and sibling-count() <https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Values/sibling-count> CSS functions on by default on all platforms. These have been developed behind the *layout.css.tree-counting-functions.enabled* preference. These features have been shipped in other browsers since Chrome 138 and Safari 26.2.
