When I set fiddler up to "Decrypt HTTPS" in the tools options, it seems that the browser (IE, Firefox, Chrome) no longer does any CSS formatting on the page.  If I choose not to decrypt, page returns to normal.  It seems that the browser won't render "insecure" content while this is running.  How can I get both HTTP and HTTPS traffic at the same time and have the page look like it normally does?

More detail.  I am using fiddler v4.4.9.2 and latest browsers.  All browsers experience same issue.  I'm trying to get a trace for a website that is not hosted locally on my machine.  Basically it's a real website and I am trying to have someone send me a fiddler trace to compare 2 different geographical locations so we can see where a delay is.  But when I choose to decrypt HTTPS traffic, the formatting is so bad, we can't even navigate through the website to initiate our test.

If you want your browsers to render content which was re-signed by Fiddler (e.g. your CSS), when asked "Do you want Windows to trust Fiddler's Root Certificate" choose "Yes."
