FPCentral: Unacceptable "Accept-Encoder" value?
Open a Tor Browser with the "Standard" Security Setting and then go to http://ngp5wfw5z6ms3ynx.onion/fp and pass the tests.
The "Accept-Encoding gzip, deflate" value is considered "unacceptable".
I wonder whether that's an error from FPCentral.
(BTW there should be a new component for FPCentral)
