I am struggling with a Windows 10 Pro version 1709 machine. When I am connecting to my ADFS form IE11 and I start capturing with fiddler, it will error.

I reset the certificate, I disabled proxy in the options and I also tried disabling WIA. When I access from Chrome, it works fine but with IE11, it does not matter what I do, it wont work. 

As a test, I created another virtual machine with same characteristics, and it works just fine. The only thing I did different is that on the machine that is not working, I did not run IE setup, on the other one that works, I did it.

 

 

I've noticed very recently that SNMP Service on Windows 10 seems to run constantly on my Windows 10 PC System. The Task Manager shows it consuming 15-20% of CPU resources on a regular basis. I want to kill the service but something on my system is probably dependent on it.

Is it Fiddler or should I look elsewhere?

Thanks for reading!

Hello,

Thanks

 

Hello,

this might not be directly related to Fiddler functionality, but I've been trying to cleanly reinstall Fiddler with no luck. What I did:

- I removed the extracted `fiddler-mac` directory from my `/Applications`.
- I removed `Fiddler2` directory from my home dir.
- I uninstalled Mono.
- I installed Mono and extracted `fiddler-mac` ZIP archive again to `/Applications`.

When I run `mono Fiddler.exe`, Fiddler keeps maintaining its previous UI states (window size, column-widths, toggled options, etc.) and it doesn't even reset the "About" info, i.e. "You've run Progress Telerik Fiddler: 32 times." instead of resetting the count to 0.

Are there any Fiddler-related preference/config files stored somewhere which I may have missed to remove? (I have looked into `~/Library/Preferences` and `"~/Library/Application\ Support"` to no avail)

Hi ,
How can I decode the  WWW-Authenticate header in c#.
I have the following header :
Authorization: Negotiate TlRMTVNTUAADAAAAGAAYAIAAAAAYABgAmAAAAAYABgBYAAAADAAMAF4AAAAWABYAagAAABAAEACwAAAAFYKI4gYC8CMAAAAPffbxvOGkL8ns+08wCF8mpUcARQBSAHMAawBhAHIAbgBpAFMASwBBAFIATgBJAC0ATQBPAEIATABmpA4p85r6qgAAAAAAAAAAAAAAAAAAAADhTsbpNSiV0RYcgZydNiGaRJqQVfHQAM80vSRnAZubLRwjwE2TnLrY

I (guess), that the information presented in the "Auth" tab is the decoding of this header.
A'm I correct ?
How can I do it in C# ?
thx
Sagi

I upgraded to v4.6.2.0 and the HTTPS decryption option is causing sites to fail to load in my browser. I have tried disabling and re-enabling decryption without any success. This was working before the upgrade. Does anyone have any suggestions?

Hello, I have downloaded Fiddler for Mac from this link: https://www.telerik.com/download/fiddler and have followed the installation instructions regarding mono and placing fiddler.exe in a writable directory. When running "mono fiddler.exe" from my terminal, Fiddler starts up. However, it is not automatically capturing web traffic like I am used to it doing on Windows.

Is there some other step that I need to perform on Mac for it to start capturing web traffic?
