Broadcast messages don't show in admin console
Summary
With Firefox the broadcast messages in admin don't show any old (or current) messages, so it's impossible to edit, delete messages. It's working fine with chromium
Steps to reproduce
Go to admin interface, select “Messages”, add a message (if you don't have any). After that you can see no message list
What is the current bug behavior?
The message board list are empty.
What is the expected correct behavior?
The message board should show the list of messages.
Relevant logs and/or screenshots
Here a screenshot of the webdev tools of firefox, pretty sure it's the problem
