 From https://bugzilla.mozilla.org/show_bug.cgi?id=1404608, a patch was
 added that breaks user agent spoofing. This patch is small and reverting
 it will fix this issue. Please fix this regression.

 The main problem is that users who have JS disabled are largely protected
 from platform fingerprinting. The lack of spoofing makes it so that even
 those users can no longer hide their platform. I do not want to be the
 only person who shows as using Linux on some of the sites I visit.

 Please fix this issue.
