someone made an addon that adds JPEG XL support to Firefox and Chrome :D https://github.com/zamfofex/jxl-crx
@noiob Ooh, I did not know about JXL but it sounds very cool. Seriously puzzled by "lossless JPEG transcoding: about 20% smaller" — this seems like either an amazing breakthrough or a damning indictment of JPEG and I can't figure out which.
no animation support though (it'd probably not be very performant so it's understandable)
