In general, Mozilla Firefox supports the AVIF file format. However due to some additional settings configured, image gets delivered in JPEG/WEBP format.
If an image is delivered in JPEG/WEBP but is expected to be delivered in AVIF, please check the additional browser settings as described:
1. Search about: config in Mozilla Firefox and click < ENTER >.
2. Search for the parameter image.avif.enabled if it is set to 'true' or 'false'.
If this parameter is set to 'false' , the image will never be delivered in 'AVIF' file format and will always show as 'JPEG/WEBP'
