Comment # 2 on bug 1230500 from Wolfgang Rosenauer

Also thanks for the pointer to the forum because the AVIF hint could be useful.
Apparently the website requests those pictures with parameter fm=avif which are
displayed black in FF 130.
When I fetch the same URL without this parameter I see the picture.

When I google for Firefox AVIF support I find articles it should be supported
since Firefox 92. But then there is this bug entry at mozilla:
https://bugzilla.mozilla.org/show_bug.cgi?id=Avif

So I'm a bit confused right now.
