Thanks Alice for filing the bug!

For regressions that you think should be fixed before release, please add tracking-firefox-? flags. Thanks!!!

I think this fixes bug 754520 as well.

Should this have a test?

Comment 8

[Robert O'Callahan (:roc) (email my personal email if necessary)]

Yes, but writing a reliable test would not be easy...

Comment 9

The status flags are a bit confusing since 14 isn't actually affected until bug 681192 is uplifted to Aurora (if it's uplifted). Tracking nonetheless.

Bug 681192 is not being uplifted to Aurora (and if it was, we'd uplift this fix along with it).
