For the Accept-Encoding header, which value is the right one: "gzip, deflate, br" or "gzip, deflate" ?

Hmm, on my instance of fpcentral, I get "gzip, deflate", but on https://fpcentral.irisa.fr/fp I get "gzip, deflate, br".
I'm not sure why. Maybe this depends on how the web server was deployed?
There are two preferences: network.http.accept-encoding and network.http.accept-encoding.secure which have gzip, deflate and gzip, deflate, br as respective values. So, it seems the answer is "it depends".
