Unable to open in FireFox

Description

We have a new install of 3.0.3

It works great in Chrome & Edge, but doesn’t open in Firefox 74 (Windows or Mac)

https://chat.chapelridge.ca/home throws an ‘uncaught exception: undefined’ error

Thanks for any pointers.

NVM – turns out this was due to enabling an iframe option inadvertently which broke the sign in page. Browsers that were already signed in had no problem!
