What specific section or headline is this issue about?

No mention of Firefox mapping to webkit vendor

What information was incorrect, unhelpful, or incomplete?

The browser compatibility within the MDN font-smooth has not mentioned Firefox 128 and later supports -webkit-font-smoothing: antialiased (by mapping to -moz-osx-font-smoothing: grayscale).

What did you expect to see?

The browser compatibility (font-smooth) table updated to reflect this change.

Research direction

Start with the MDN font-smooth page and its browser-compatibility data, then read the linked Firefox references to confirm the version and mapping for -webkit-font-smoothing: antialiased. Update the compatibility table to reflect Firefox 128 and later, and verify that the rendered data shows the expected support information.
