Suspicious Message warning

I am getting a suspicious message warning for a techbargains.com newsletter sent to me on e-mail. This never used to happen. The text says “(You can permit them using “Permitted URLs” button)”. When I click the “Permitted URLs” button and then continue, nothing happens and I still can’t open the message. How do I overide the warning and get the message opened???

You have to enter the url that is permitted e.g. click add enter the url and click OK, see image.

This however, only works if the reason for the suspicious message warning was an iFrame and you didn’t say what was the reason for it.
