I tried logging into my Telerik account using the latest FireFox browser and there are a boatload of error messages in the developer's console. I could not do it. I had to go back to Chrome to login to this website.
Also, the latest version of Fiddler which I downloaded and installed yesterday will correctly capture my Intranet Chrome traffic but none of my Intranet FireFox traffic. Where is the support for the FireFox web browser?
