Hello Forum,
I work for a company called ePay and I was wondering if someone could assist me with a certificate issue.
Our company uses a Digital Certificate with our customers and it seems we might be having some compatibility issues with Fiddler.
My question is the following:
Since we have a certificate installed and imported into the browser (e.g. IE10) and then Fiddler adds a Do_Not_Trust_FiddlerRoot Certificate which causes the compatibility issues. I read that a fix would be to move the certificate from the personal folder to the "Trusted Certificates" folder, but I want to confirm this would be the ideal fix and that I wouldn't disrupt or disconfigure any settings in Fiddler.
And my second question is;
What type of problems could we expect if the Do_Not_Trust_FiddlerRoot is left on the personal folder? (problems with OUR certificate)
And my last question is:
Would any configuration be lost if they DELETED the Do_Not_Trust_FiddlerRoot certificate?

Thanks for the help.

Hello, I am using Fiddler and have a filter set to capture sessions. I have not used it in a few weeks and when i went on today, it is not capturing anything. I have checked all my settings Capture traffic is enabled, i went through all the options and it is not recording anything. i tried it on ie and on firefox and its not working on either.

Environment: Fiddler 4.4.6.2 64-bit on Windows 8
Proxy server in the browser was manually set to localhost:8888.

Problem: when Fiddler is told to NOT capture traffic (the icon in the left bottom corner disappears) Fiddler still captures traffic and displays it.

Basically there is no way to temporarily disable capturing other than disabling proxy in the browser. This is very inconvenient, especially in a VM environment.

Hi,

I've a issue with a computer when I launch Fiddler.
Every URL address I want to request is bloqued while capturing is enabled.

If I stop capturing, URL request are passing.

My version is up to date,

I've tried to unistall and clean it, then re-install it without success.

What is strange about it is that I don't have this issue with an other computer with the same configuration, params, and antivirus options.

I've only found one topic about it on google, and the guy solved it with an uninstall (unfortunatly it doesn't help me there :/)

For information, in help > about, it's written 'No Gateway' on both computers.

If you have any information or tips to help me to solve this matter I'ld be very grateful ;)

Hello,
we are trying to automate web browser control through powershell and we are using FiddlerCore to get the time statistics. Basically trying to get the total time taken by a website to finish loading.  

We call start-Fiddler to use it as proxy and then create a browser control.
Now we Navigate to page and then call $output = Receive-Fiddler.

Now there seems to be a problem with output returned through this command "Receive-Fiddler". It basically returns an array of requests made and the time statistics [ ClientConnected , ClientDoneResponse ]. often I see the ClientConnected , ClientDoneResponse is coming as Null. Again this is intermittent but can happen atleast  5-6 times in 10 tries. its easily reproducible.
 ($result[0].Timers.ClientConnected )


has someone reported this behavior? is there an better approach than what we are doing?

thanks for your help

I have connected an iPhone to my Win 8 machine and configured Fiddler to with instructions found here http://blog.brianbeach.com/2013/01/using-fiddler-with-iphoneipad.html

So far all seems ok in that when I access a website on the iPhone its logging it and I can see where its going etc. I then need to monitor https requests by that I mean a site in the format of someSite:443.

When I access an app using this mechanism the application freezes and returns an error (cant connect) which I assume is to do with the traffic going through port 8888 - what additional steps do I need to take in order to capture the URLs that the app is hitting?

Hello,

FiddlerCap was used to work smoothly, but since I updated to latest version, I always get the following error when I start capturing a session:

503 Service Unavailable
Failed to resolve the name of server fiddlercap.fiddler

I attached a screenshot.

Thanks,

I have installed Mono 3.4 for OSX and Fiddler2 for Mac from http://fiddler.wikidot.com/mono.

When I attempt to open Fiddler.app...it just hangs and I have to force quit it.

Any help is much appreciated.

I installed Fiddler to view the traffic to/from a local application via http://localhost:8888/.. I installed Fiddler 4.4.6.2 but am a bit confused by a couple of things.

When I run my test that accesses my app (on http://localhost:8888/.. ) I see the traffic in Fiddler, but the client I am testing crashes because it seems to be getting back something from Fiddler Echo Service instead of the actual response from my app. How do I stop that?

Secondly, even when I turn capturing off (File > Capture Traffic), it is still capturing traffic. I have to exit from Fiddler before it stops.

Is there something else I am meant to do here just to get Fiddler to view the traffic, not modify it, and to stop capturing when I ask?

Thanks!

Hi everybody,

I use Windows 7 with a dark theme. Fiddler works great with it. 

Problem is, when I save a .saz file and then load it, Fiddler shows a white highlight on all the requests. That highlight makes the request unreadable. I have no idea why it does this or whether the highlight has any meaning. It doesn't show that highlight when working normally, only when loading a .saz file.

Screenshot attached.

Any idea how to get rid of this?
