+To ensure compatibility with these changes, the [Vendor-prefixed transform properties](#vendor-prefixed-transform-properties) and the [Vendor-prefixed transition properties](#vendor-prefixed-transition-properties) are disabled in the Nightly release.
+These changes are described in the following sections.

+#### Vendor-prefixed transform properties

+The `-moz-` prefixed [CSS transform](/en-US/docs/Web/CSS/CSS_transforms) properties have been disabled in the Nightly release via the `layout.css.prefixes.transforms` preference being set to `false` ([Firefox bug 1855763](https://bugzil.la/1855763)).
+Specifically, the disabled properties are:
+
+- `-moz-backface-visibility`
+- `-moz-perspective`
+- `-moz-perspective-origin`
+- `-moz-transform`
+- `-moz-transform-origin`
+- `-moz-transform-style`
