I'm trying to edit fields through Mac Firefox version 49.0.2, even with no addons configured.
When I click to deselect the "OBiTALK Settings" check-box for an item, it does not auto-check the "device default" check-box.
Using Safari, clicking to deselect the OBiTALK box does auto-check the device default, which I can then uncheck and then edit the value.
Anybody else hit this problem?
