As I mentioned in my review of Bitdefender Total Security 2013, I ran into an issue where Mozilla Firefox would display a certificate error on my screen when I accessed my Gmail account. In fact the error appeared whenever I access any page within Google, and only Firefox displayed the error, and no other Web browser.
After some quick research into the problem, I managed to trace the problem to Bitdefender Total Security 2013, and then find what tool within that security suite was causing the problem. Below are the steps I used to solve the issue so I could access Gmail from within Firefox.
