Re: [whatwg/fetch] Accept headers in spec cause confusion (#274)

wolfbeast left a comment (whatwg/fetch#274)

Our (UXP/Goanna/Pale Moon) headers are currently:

Navigation requests:
`text/html,application/xhtml+xml,application/xml;q=0.9,image/jxl,image/webp,image/apng,video/x-matroska,video/webm,*/*;q=0.8`
Image requests (IMG elements etc.):
`image/jxl,image/webp,image/apng,image/png,image/svg+xml,image/*;q=0.8,*/*;q=0.5`
Stylesheet requests:
`text/css,*/*;q=0.1`

For other requests we fall back to `*/*`

What we consider ubiquitous formats (jpeg, gif, mp4, etc) aren't presented in `Accept` headers.

Of note: we do not support AVIF so that format isn't in the headers, and we have full support for jpeg-XL so that _is_ present.
