Ann, thank you for the screen shot! As I'm sure everyone realizes, I have no way to know how things look on every laptop/PC/mobile configuration.
If anyone else would like to check their Firefox Padlock, do this:
Click Padlock > Click Right Arrow (on the right of popup) > Click More Information (at bottom of popup) > Click Security Button (at top of window)
Now, interestingly, here is what I get from my Firefox Padlock which is different from what Ann is seeing. I do not know why.
Ann, try this: Log out of Nikongear. Clear Firefox browser history/cache/cookies. Then log back into Nikongear and recheck the Padlock.
