I think this is an intentional change that the <select> dropdown uses native styling with e10s. This is related to bug 910022 but not a dupe since this form doesn't specify any non-default styling.

Mike, do you know if we intentionally change the default styling in e10s to be more native?

Why do we need to make this change e10s specific ? Native styling looks better and worth the change no matter e10s is on or off.

We're in the process of merging the e10s and non-e10s backends for the <select> dropdown, which should solve this.

marking fix-optional to get this off the triage list, we'll track bug 1300784 instead.
