That sounds promising. Is that a bug with NGINX or do I need to get my hosting company to 2021-04-25T07:34:33-07:00kevin143https://support.mozilla.org/ru/questions/1333684#answer-1408709<p>TyDraniu,

</p><p>Thanks for the reply, but are you able to explain why Edge / Chrome display .webp but Firefox doesn't?
</p><p>Did you make the change to Firefox to be able to see the .webp images? I was hoping it was something that needed doing at the server side (or a bug) so that everyone would benefit from the performance improvements
</p><p>Let me know - thanks

Do you get WebP for this image in both browsers?

I have reported to the server team. This may explain why I presented the error to you all as a problem just with Firefox, but when you all looked - the problem was in all of them.

</p><p>Unless you disable webp completely, Firefox include image/webp in the "Accept" request header. I assume the CDN looks for that when deciding to apply WebP compression "on the fly," but I don't know what else it might be looking for.

</p>Did you make sure the WebP is enabled and also not blocked by an extension ?

</p>
<ul><li> about:config =&gt; image.webp.enabled = true
</li></ul>
<p>Firefox should send an image accept header that includes "image/webp" as a supported image format.
You can possibly check this in the Network Monitor or Web Console.
