Comment 1

[Richard Newman [:rnewman]]

None of my changes in that build touch Fennec, so this should apply to inbound, too.

Comment 2

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

Reminder to self to try on current nightly

Comment 3

[Gian-Carlo Pascutto [:gcp]]

This still occurs. Low priority because I think it's harmless. The Gecko/JS side of handling Preference requests should be more robust about not existing preferences.

Comment 4

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

Still occurs on the nightly.  Thanks GCP.  Not going to nom due to comment 3.
