Gmail security issue?

When I have my inbox loaded, even though it says https, I click on the gmail icon next to the address bar and it says: This website does not supply identity information. Your connection to this website is not encrypted.

At the logon screen, it says it's encrypted and identifies it as google. It's only after I'm logged in do I see that status. Any ideas?

Edited to add:
1) I do have Better Gmail 2 extension enabled. This runs scripts to tweak gmail. Do you think that has anything to do with it?
2) I disabled Better Gmail 2 and still same problem. Tried Gmail on another laptop and the certificate reads fine. Both using Firefox. Can't figure out why laptop #1 won't show the security certificate, even though it says https.


================================================
Solution:
Had Google Gears enabled (for offline access to gmail, reader etc). Once I disabled that, I am able to get a secure connection. Well, I'm able to pull the google certificate and the site reads as secure, so I'll assume it wasn't secure before. With Gears enabled, I was however able to get a secured connection using Chrome. Makes sense since this is a firefox addon, but doesn't make sense as to why it would make the gmail connection insecure. Oh well, bye bye gears.
