Firefox unencrypted warning
I was logging into a secured website containing private information. Firefox then warned me with the following message:
Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by third party.
I was pretty sure the login page is on a secure http connection (https). See picture below:
After searching on google, I found out that the login form is submitted (action) to a JavaScript. Firefox does not have any idea what the JavaScript is doing to the data sent.
