Netflix Error F7121-1331 on Mac/Linux [solved: RFP's HTTP Header is spoofed as Windows & NF no longer chills] [1610762]

See original GitHub issue

Hello all,

I am running FF ESR91 from Debian Stable. Without user.js Netflix is playing fine. When I apply user.js (the version for ESR91) and the override recipe user_pref("media.eme.enabled", true); Netflix videos can not be played. They start loading (without the override they do not) and then Error F7121-1331 is shown.

Does anything else need to be overriden?

I think we have some progress here, but unless @tomrittervg actions it (or feeds it to a first bug apprentice), it’ll never happen and languish at P5, and that’s understandable, not because it’s a difficult patch (it’s pretty simple IMO), but because RFP is for TB, and TB don’t really want this (and it’s moot given DRM is blocked and AFAICT this is about the only instance of HTTP Header spoofing causing an issue), and IDK if tom et al really want an extra code path/divergence

so IDK what will happen ¯\_(ツ)_/¯

Okay so I set the OS as macos and FF version to 91. RFP is enabled with user_pref("privacy.resistFingerprinting", true); (That is the only pref in the user js for this profile). The user agent now is : Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14.3; rv:91.0) Gecko/20100101 Firefox/91.0

edit - That is the user agent in the http header

And netflix works
