Removing interception certificates via Fiddler option "Remove Interception Certificates" only removes them from Personal and Trusted Root Certification Authorities. Certificate that is located in Intermediate Certification Authorities is not removed. This certificate is not trusted after using "Remove Interception Certificates" and has status "This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store".
sigcheck -t[u]v doesn't show any warnings.
Tested this on both Windows 7 and 10. Tried refreshing certmgr, restarting it, and rebooting machine with no success - intermediate certificate is still there.

1) Please try to make FE remember its window state so it can open at same size. Opening maximized is just rude.

2) Please try to store current settings when they are changed, and use them when opening... every time I relaunch, I have to check the Enable Auto Responses box again

I want to monitor one .exe application that takes in HTTPs proxies as argument and sends HTTPs requests towards some external site using those proxies. If i select in that program that i don't want to use proxies but rather localhost IP, Fiddler easily tracks it down, but when i start using those proxies as an argument instead localhost IP, none single request is being shown. Is there any way to fix this and show this traffic from this app when using proxies? Thanks in advance.

I installed Fiddler on mac on High sierra. I can start it up but when trying to start capturing nothing happends. I have enabled https etc liked described ? - what must be done?

Hi,

I need a traffic to be intercepted with FiddlerCore and then passed to Fiddler (like in a chain, no matter which is first, FiddlerCore or fiddler)

What shoul i set in  FiddlerCoreStartupFlags or anywhere else to have it working?

 

Thanks you

I am sending my request but i am not able to see response in json section though json in request section is visible

I cannot find a very useful function "Breakpoint" in the Fiddler Everywhere. Does the Fiddler Everywhere contain this feature? 

alert “do not find usb key” and fiddler stop to work？

In "OnBeforeRequest()" event, I want to download a URL and then return it as "oSession.LoadResponseFromStream()".

 

I want to redirect to or something like that. What is the Fiddlerscript function to download URL in code and return it as body"?

You can test it here yourself: https://www.ssllabs.com/ssltest/viewMyClient.html

Just enable fiddler and allow the certificates...
