I managed to reproduce this issue using the provided steps from the Description, on latest Nightly 59.0a1 (2018-01-16) and Release 57.0.4 with Windows 10 x64, Ubuntu 14.04 x64 and macOS 10.12.

First, I accessed the following website in Responsive Design Mode: https://webmail.whatever.com/
After that, I clicked the "Add Exception" button, but nothing happened, the dialog for confirming the security exception didn't open.

I tried to narrow a regression window here, but when switching the bisection method to taskcluster, no more builds were found. 
Here is the resulted push:

I think bug 1296498 might have introduced this issue, but I'm not entirely sure about this.

Thanks for the report!  I can confirm this issue in the new RDM UI.  As a workaround for now, you could add the exception outside of RDM, but of course that's not ideal.
