Hello,

I'am getting an certificate warning on the latest update.

See picture. What is wrong here?

My previous version was signed by Telerik AD, this update used Telerik EAD?

Hello Everyone,

I am facing an issue while installing the Microsoft neXpert Performance Analysis Plugin.

Issue Background:

I have installed Fiddler v5.0.20182.28034 and tried to install neXpert but i am getting an error message from the microsoft plugin "neXpert can only be installed if Fiddler 2.2.9.4 or greater has been installed first".

Anyone faced this issue earlier, is there any other work around solution for this?

Hi! 

I am a web analyst and not a front-end developer.

I am trying to debug a site's analytics using imacros and Fiddler (I am open to another solutions that can log a traffic and autosave a log). Never done it before.
It is a 1 site that I will run using 5-10 simultaneous firefox profiles under Imacros.

What I cannot understand is how will I differentiate in fiddler which log correspond to which firefox profile since they run simultaneously.

 

VERSION BUILD=11.5.498.2403; Windows 10; Imacros Browser + Firefox Imacros 8.9.7; Firefox 49.0.2

All I get is a warning, then no program pops up.

 

mono 5.10.1.57

 

MBPro15-512:fiddler-mac peterkellner$ mono Fiddler.exe
WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all
^C

When I try to runt he Fiddler installer I get an error.

After agreeing to the EULA and specifying an install folder I get an error that says:

"A Progress Telerik Fiddler component appears to be running. Please, close all Progress Fiddler-related applications and try again."

I am not currently running Fiddler. I don't know how to look for what is considered "related."

Hi Eric,
I was a newbie to FiddlerCore.I want to capture https traffic when requested to website using Selenium and FiddlerCore in .net.Coded as below 

CODE:

CONFIG.bCaptureCONNECT = true;
 CONFIG.IgnoreServerCertErrors = true;
var cert = InstallCertificate();// getting true
FiddlerCoreStartupFlags flags = FiddlerCoreStartupFlags.DecryptSSL & FiddlerCoreStartupFlags.AllowRemoteClients & FiddlerCoreStartupFlags.CaptureFTP & FiddlerCoreStartupFlags.ChainToUpstreamGateway & FiddlerCoreStartupFlags.MonitorAllConnections & FiddlerCoreStartupFlags.CaptureLocalhostTraffic;
FiddlerApplication.Startup(desiredPort, flags);
FiddlerApplication.BeforeRequest += RequestDetails;

private static void RequestDetails(Session oSession)
        {
            Console.WriteLine("Request URL {0}", oSession.fullUrl);// getting only http traffic details
            
        }

public static bool InstallCertificate()
        {
           
            if (!CertMaker.rootCertExists())
            {
                if (!CertMaker.createRootCert())
                    return false;

                if (!CertMaker.trustRootCert())
                    return false;
            }

            return true;
        }

Could you suggest me the way to capture https traffic


Thank you

Avinash

     HI,

CONNECT mhms11.airtel.tv:443 HTTP/1.1 I see the tunnel to this address

Fiddler's HTTPS Decryption feature is enabled, but this specific tunnel was configured not to be decrypted. Settings can be found inside Tools > Options > HTTPS.
A SSLv3-compatible ServerHello handshake was found. Fiddler extracted the parameters below.
But no data after that.

Put this in fiddler   <client>;ssl2;ssl3;tls1.0;tls1.1;tls1.2 and installed certificates. This is happening for most android app. I am creating a hotspot in windows and connecting android tab. I installed. the root certificate on android. Any help to check if its certificate pinning rather than guessing which is creating this issue

I am trying to login into my application through Jmeter but when trying to get the response, fiddler displayed "Content -Type: multipart/from-data is not yet fully supported."
