Will animated JPEG XL be supported? I like to make animated images and dislike GIF for obvious reasons, but WebP is not a perfect replacement for philosophical reasons. I am eager for more programs to support JPEG XL so I can use that format for the animations that I create.
But in my experience with WebP, some programs that claim to support that format only support static WebP images. When they encounter an animated WebP, some programs only render the first frame of that animation. Due to that experience, I am hesitant to assume that animated JPEG XL images will work just because static ones do.
It does seem to be animated when I view the file in firefox. That doesn’t have to mean it works when embedded on webpages though, but I guess there’s an easy way to test that :)
Yes, there’s an “enable JXL (JPEG XL) support” toggle in the settings (tabs and browsing → media on librewolf (which is what I use too), or in ‘firefox labs’ on normal firefox).

If you want to test, here is an animated JPEG XL I made a while ago: https://files.catbox.moe/80ottu.jxl

Do you have some experimental flag enabled or something? Neither link is working for me on LibreWolf.
Regardless, it is good to know that when Firefox supports JPEG XL, it seems to support animated ones.
EDIT: I just enabled that, and both of the above links work as expected!
1. Navigate toabout:config2. Searchjxl3. Toggleimage.jxl.enabledtotrueActually, see what @mschae@discuss.mschae23.de posted below. That is likely a safer method than messing with
