fiddler

I am trying to debug an asp.net app using Firefox. Firefox tries to connect to https://www.paypal.com and I get "Secure Connection Failed" error (Error code: sec_error_bad_signature). I installed Fiddler's cert in Firefox and the local computer and current user Cert stores. I set up the manual proxy in FF to 127.0.0.1 and port 8888 and for all protocols. Fiddler captures http traffic but gives an error with https traffic. Fiddler captures https from IE fine.

What's the problem?

(Is FiddlerHook FF extension needed and what setting should it be using: auto, disabled or Force traffic to Fiddler?)

I need to see the actual requests being made from a asp page to the webservice(which calls another webservice). All these requests happen on the same local box. I ran the "proxycfg -p http=127.0.0.1:8888;https=127.0.0.1:8888" on the command prompt based on http://www.fiddler2.com/fiddler/help/hookup… >>> More
