General Discussion • Re: This websites works on Pale Moon but not Chromium! (at least for me)

Their CDN seems to serve various formats; JPEG, JXL, PNG, AVIF, WEBP. Link opening one image in one browser may not open the same image in another browser, so I suppose some negotiation bug was encountered.

FWIW, Thorium has JPEG-XL support compiled in. Stock Chromium used to have it for brief period few years ago behind a flag.

Firefox has it compiled in release build (but disabled by default) since version 152 and some forks have had it before that. So it's getting to the point it won't be much of an exclusive feature anymore.
