I have seen this issue on two sites while shopping online. When I go to checkout and click "Checkout with Paypal" the green padlock will show in firefox for a brief moment and then I get the gray globe.
I know very little about certificates but when I click on the gray globe - more information - media I see an image that is not https. If I then click that image link in the box and click block images from that site and reload the page I can now see the green padlock.
If you want to give this a try yourself go to homedepot.com, add something to your cart, click checkout now and then click check out with paypal. When you look at the certificate you will see the non-https image link. If you click that link and then below click block images from homedepot.com and then reload the page you will see the normal green padlock.
My questions are, can you see this with other browsers or is a firefox only issue? I did give IE a brief go and I got a pop-up asking me if I only wanted to view the webpage content that was delivered securely. Is this a major issue? Would you enter your PayPal information without seeing the EV certificate or a padlock?
Edit: Here is a link to what the green padlock, gray padlock and gray globe mean in firefox. »
