Firefox Warning

Why do i sometimes get this warning in firefox?
You have requested an encrypted page that contains some unencrypted information. Information that you see or enter on this page could easily be read by a third party.

Answer #3
is it something you have to worry about?
Answer #4
Nope, it’s just a warning letting you there’s data on that page that’s encrypted, and they ask you if you want to continue or not. It’s just a “If you accept and get your information stolen, it’s your fault”. type of thing.
