Mass confusion approaches?
Back on 27 June Firefox announced that their “mixed content blocker” was available in the Firefox Beta, and was on track for general release with Firefox 23. But, look at the indicator they are using:

Here’s an IE10 equivalent, displayed at the bottom of the screen when a problem site is encountered.
It’s great that Mozilla are actively searching for sites that are being broken by the upcoming mixed content blocker, and it’s great that they are introducing this protection, but my personal opinion is that the size and position of the indicator they have chosen to use make it far too easy to miss, and users are going to be confused when sites they are visiting break.
