First comsec said that I need to use "comsec" in the url, not "commsec" as only "comsec" is the secure site - not so sure about that as I thought there would be re-directions etc in the background to take care of that. Once past that, I got a more satisfactory reply in that some frames on pages are secure, even if the whole page is not.
In Firefox, on the My portfolio page, right click on the yellow area which contains total cost, market value, etc then select "This frame" / "View frame info". The fact that this information is also displayed further up on the page - I let that go. Buy/Sell pages are secure when you get to the point of sending the information - I usually use webiress to trade but I'll try to check that next time using comsec.
