When I want to login at my online bank account, I get the warning that:

'Although this page is encrypted, the information you have entered is to be sent
over an unencrypted connection and could easily be read by a third party.'

I got this reply in the mozilla security newsgroup.

The "action" for this form is not https but rather is javascript.
The browser doesn't know (prior to interpreting the javascript)
what the javascript is going to do with the form data, so it assumes
the worst, and you get this warning.  Perhaps the warning should say
"The data from this form is being sent through a script rather than
directly and immediately through secure https, and so I cannot be
sure that the data will be sent securely to the server."

In this case, the javascript appears to me to post the form data
securely to the server.

Communicator 4.x handled this case by waiting to see whether the
subsequent outgoing network connection done by the script was http
or https, and warning only if it was not https.  But mozilla warns
before the script is run, as I understand it.

Mozilla can determine that the information is securely transmitted by the java
