 Despite updating `general.useragent.override` to match ESR 60 (done
 according to comment:16:ticket:25543) the platform part is not spoofed to
 Windows on my Linux box.

 Now, that is intentional, see:
 https://bugzilla.mozilla.org/show_bug.cgi?id=1404608.

 So, we probably should not set `general.useragent.override` at all anymore
 and just rely on the settings we get with `privacy.resistFingerprinting`?
 Because if we explicitly set it to the Windows UA but then don't get that,
 this is weird.
