Context: Even though Chromium has native support for AVIF, a very nice image format, Microsoft goes out of their way to remove it from Edge, which is a chromium fork. Jpeg XL (JXL) (not to be confused with Jpeg (JPG) or Jpeg 2000 (jpg2k) ) is another nice image format, which, IIRC, is only supported in Firefox.
Since when can apple play it?
Safari got full support in march 2023
The newest version of edge which is currently in beta also supports it
