Sorry, I don't think that is a message from inside Firefox, the wording doesn't sound correct - at least the beginning of that message. My "gut" thinks that is a MSN Live message to explain and compensate for their lack of security with a re-direct from a secure domain to an un-secure domain. (the end of that message)

{Ctrl + Shft + J} will open the Firefox Error Console - I'm curious what Firefox has to say about that situation. If you find the error message for that domain, you can right-click the message to copy it and then paste that error message here.


Maybe TonyE or cor-el will be more familiar with the situation at Live and maybe at Google Reader, I don't use either of those services and have never seen a message like that myself.

I had a whole bunch of messages in the Firefox Error Console. I cleared it and then opened up hotmail in a new tab and checked the Error Console again and had a whole lot of messages. I am not sure which ones I should post, but here are the ones that look more relevant.
