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.
