I installed Fiddler several months ago (Windows 7) and didn't use it much. I uninstalled it. In the last few days, my Trusteer app has been complaining that some websites I normally visit have a bad certificate.  I have searched all files and the registry on my computer and can't find any residual Fiddler files. I deleted the root and other certificates labeled "DO_NOT_TRUST ..." But, I'm still getting this error (see attached.) Same behavior in IE and Chrome. Something is stuck. Please advise how to remove and restore normal operation.

I can no longer see the traffic from the chrome browser, i have checked for filters etc and there are none.
As you can see from the image attached the chrome browser is not showing could this be the reason and if so what is the fix.

Hi. I use windows 8.1 and need to debug my traffic from winstore apps to remote server. 

I sucessfully used fiddler for these purposes, but it unexpectedly stopped working.
 
Now I see next situation: after running fiddler all my winstore apps unable to send data to remote server. 
From my app I see that after submitting data simply nothing happens. After timeout expired, I get httpexception.

Of course, I know about windows 8 restrictions for winstore apps regard local traffic. And I've used enable loopback utility for this case. 
But recently it stopped work with strange behavior: on start app sucessfully got installed applications list, but unable to refresh it. 
When I press "Refresh" button, I got next error:
Unable to use NetIsoEnumAppContainers to get AppContainer list.
Error Code: 0x5

Attempting manual registry crawl; some information will be unavailable.

And I unable to see any data from my or installed app. Also any installed app is unable to send and receive any data with runned fiddler. 

 I've tried to uninstall\reinstall fiddler but not helps. Do you know something about this problem? Can you help me to solve it?

I'm wondering if there's a way to force a client reconnect in an extension? I looked through the network flags and didn't see anything but I did find the fiddler.network.timeouts.clientpipe.resuse setting. The extension I'm working on spins up background threads to make it's own webrequests against an F5 however I'm getting locked to a specific machine due to using the same client connection. I'd rather not muck with the preferences and instead force a reset before each new web requests. Is there a way to do this?

Thanks in advance!

I was curious on the SSL settings utilized by Fiddler when https debugging is enabled. Is it limited by the Operating System on SSL protocols (SSL vs TLS versions), Ciphers and digest algorithm? Is there an order of preference for each criterion, starting with lets say the highest (something like TLS 1.2+GCM/AES 256 bit+SHA384) ?

Hi Eirc,
     Thank you for your wonderful Fiddler first of all.
     I want use Fiddler Script to save or export the packets I'm interested in automaticly.But I don't know how to do.
     
    For example,I need to save all the packet to the destination hostname 'www.xxx.com'.
    I think I can add the auto save code like this:

    if (oSession.host.indexOf("www.xxx.com") > -1) {
     //save or export the packet to my own file
   }

   Does Fiddler Script supports write data to local file,And how to do it ?

   Maybe there's some other way to export or save the specific packets automaticly ,would you please tell us how to ?
   
   Thanks.

Stephen
   

Currently, I can view all traffic (both HTTP and HTTPS) from my Win8 Phone when browsing the web. However, when I launch a game, I am unable to see any of the calls made. Even HTTP Connect calls are unable to be seen. I'm currently checking this on an actual Win8 Phone and not an emulator. To see the calls appropriately, will I need to be using the emulator or will this make a difference?

Thanks,
Mason

Hello,

I'd like to monitor traffic generated by an android app. The app is only sending part of the traffic through the default android proxy (which is set up on the wireless connection as documented on http://docs.telerik.com/fiddler/configure-fiddler/tasks/ConfigureForAndroid). However, I also want to monitor the part that is not going through the default android proxy.
How can this be achieved? Maybe by using iptables?
