Thank you for this. Firefox should support jpeg xl.

Site favicon not effective

After Googles braindead move and Mozillas braindead following of it, it's really great that this exists! :)

Great addon. JXL needs native Firefox support but until then this is a good solution!

Doing what Firefox can't because they are too scared of being different from Chrome.

It's all over for JPEG 2000 (only darkness now)

Finally I got support of JXL in my browser!
