Mozilla issues Intent to Ship: JPEG XL is coming to Firefox

Mozilla posts an Intent to Ship announcement planning to enable JPEG XL image support by default in Firefox. If it lands, a decisive turn in the browser camp's years-long format split — Chrome removed JPEG XL, Safari already shipped it. Surfaced through the Lobsters front page (25 entries in the current feed).

An Intent to Ship is process intent, not a shipped feature; timelines and scope follow Mozilla's later announcements. The BitShovel snapshot carries only the title and link (the page body could not be fetched), so the original announcement remains the source of truth.
