I did some simple testing on accounts.google.com, YouTube, 
calendar.google.com, Google Maps in a JHBuild environment on FreeBSD. 
After disabling quirks with a dconf command and confirming user agent 
was set to the default value with web inspector, I saw no difference on 
YouTube and calendar.google.com. accounts.google.com worked, but it 
showed the old login page instead of the new version introduced 
recently. Google Maps was only available in lite mode and earth view was 

Changing video quality on Youtube sometimes crashed WebKitWebProcess 
with SIGABRT or SIGSEGV, but this happens regardless of quirks.

Software versions:
  * FreeBSD 11.0-RELEASE amd64
  * JHBuild moduleset gnome-apps-3.26
  * Epiphany 3.25.1-15-gbde8aee66
  * WebKitGTK+ 2.17.2
