Whatever your last update included, it did something to change the .cert because I can't view any webpage with https now. It worked fine but after updating this morning it won't load anything no matter what I do. I even deleted any and all old .cert's and generated a new one and trusted it and nothing. Thanks for that......
Nothing in the last update should do that indeed. Did the Reset Certificates work for you or are you still experiencing this problem?
With more details, we can get you working again. https://groups.google.com/group/httpfiddler is probably the best place to start, but the Actions > Reset Certificates command is the most likely to get you sorted.
