Netflix have recently (and also, finally) started supporting Firefox
on Linux, which is great for Fedora users who want to watch Netflix
without having to install Chrome or Chromium.
However, there's a catch: our default Firefox user agent is blocked
If you try to use Firefox on Fedora to watch netflix, you'd get an
error message that silverlight is required.
If you then change the user agent to "Mozilla/5.0 (X11; Linux x86_64;
rv:52.0) Gecko/20100101 Firefox/52.0" (you can set
general.useragent.override in about:config) and try again, netflix
will work without any problem.
I think we should fix this, because it's silly to force user to
install a non-default browser to do this kind of thing.
There are two ways we could fix this:
1) Stop using a custom user agent. This also has the benefit of
making Fedora users a bit less trackable, but the downside of not
having a way to measure active Fedora users online (which is why the
custom one was re-introduced, iirc).
2) Someone with an official position within Fedora / Red Hat could
email Netflix and ask them to stop blocking our custom user agent.
I think Netflix's rationale for blocking non-upstream user agents is
that their "help page" says "Supported on stable, official release
builds from Mozilla. Non-Mozilla builds are not supported.".
Considering the fact that most Linux users (and especially Fedora
users) don't run the mozilla builds, and that Firefox in Fedora meets
all of mozilla's branding guidelines to be eligible for officially
calling itself Firefox, I think that limitation is silly, so we
probably should convince Netflix to change their user agent blocking

we're aware of this issue. We're currently working on the solution #2.
Netflix is not blocking non-upstream user agents, they're blocking
Fedora specifically! Replace Fedora with a random string and it will
work. This is strange and we wanna find out why they're doing it.
Note that they do the same with Chrome where we have a Fedora user
agent, too. The reason why it works is that we put a logic in the user
agent extension which removes Fedora from the user agent for the
domain. We could do the same for Firefox, but I think it's
better to solve this with Netflix.
