Comment (by kevinoid):

 For reference, I just submitted
 https://bugzilla.mozilla.org/show_bug.cgi?id=1489903 to address
 privacy.resistFingerprinting=true causing general.useragent.override to be
 ignored.

 Personally, I think TBB should send a Windows User-Agent from desktop
 browsers and Android from mobile, since it strikes a good balance between
 feature detection and a minor benefit to fingerprinting resistance.
 Regardless of the TBB default, I think users should be able to override it
 by configuring general.useragent.override for themselves, since they may
 have specific reasons for doing so.
