My secure site icon/site identity button seems to have reclassified many sites I visit. My email login now only rates a grey padlock, and even firefox help's homepage only got a grey globe. Even when banking I had to go through multiple pages before getting a secure icon. Sometime hitting the refresh button will change a grey globe to a grey padlock. What's going on, and should I be worried about security? The problem does not seem isolated to a single website. I've already disabled a number of add-ons, but am continuing to experience this problem.
