Firefox updated itself yesterday and now it's sometimes reporting a Protocol Error when I try to open a website. Not always and it offers a Try Again button which usually works. So its not a serious problem for me but it is annoying and it suggests there is a fault in the new build.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
