I am using Firefox 5 with Ad Block Plus and NoScript. Both are disabled at the time of testing.
I received the following message when clicking 'Email'
This content cannot be displayed in a frame

Clicking the link works fine, but I'm wondering why this his happening and how to prevent it. I could not replicate this in Google Chrome.
