- The {{cssxref("::details-content")}} pseudo-element is now enabled by default. It lets you style the content of the {{htmlElement("details")}} element.
([Firefox bug 1941406](https://bugzil.la/1941406)).
- The {{cssxref("::marker")}} pseudo-element can now be used to style a list item that has been created using the {{cssxref("::before")}} or the {{cssxref("::after")}} pseudo-element. This is achieved using the [`::before::marker`](/en-US/docs/Web/CSS/::before#beforemarker_nested_pseudo-elements) and [`::after::marker`](/en-US/docs/Web/CSS/::after#aftermarker_nested_pseudo-elements) selectors.
([Firefox bug 1980215](https://bugzil.la/1980215)).
- Multi-pass grid track sizing is now enabled by default and follows the algorithm outlined in the CSS Grid specification. In the multi-pass algorithm, columns are sized first, then rows; percentage values are resolved after the container size is known. With this default support, [percentage-based](/en-US/docs/Web/CSS/grid-template-rows#percentage) row tracks and grid items with aspect ratios will now be sized correctly in more cases.
