Actual results: Firefox showed me Developer Console without any warning. Expected results: Firefox should warn me about the great power it has, with great power comes great responsibility.
We're aware of the issues with this type of problem in Facebook. Could you provide links to other scams so we can check that our solutions work for as many cases as possible?
The example I had was for Facebook and they are being removed, if I find some more, I will post it here (or in the main bug).
As summarized, this is more a dup of bug 953166 or bug 691452, but bug 994134 is our targeted solution for the pasting-based attacks.
