Hello,

I am new with Fiddler.  Please bear with my inexperience. :-)

My result panel is polluted with a Chrome extension 500 error. The URL is http://127.0.0.1:55296/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg.  Please find a screenshot attached.

 

Could you please tell me what my filter options would be?

I have tried:

* Filter rule: Request header > Hide if URL contains: "/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg"

* Script rule:

if ( oSession.url.Contains("/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg") ) 
        {   
            oSession["ui-hide"] = "yup"; // "The "yup" value is unimportant"
        }

 

What am I missing?

 

Thanks in advance for your help

 

 

Hello, first time poster. 

I work for a mobile games company, and in my previous job we used Fiddler and custom rules for creating quite extensive QA debugging tools. 

However, the company I now work for severely underutilized 3rd party tooling in their processes so i'd like to work on writing custom rules in Fiddler for my team to use. 

Here's the kicker- While I understand the fundamentals of how Fiddler and web debugging works I have no prior knowledge of writing code languages in any context. 

I'm hoping someone here will be able to provide advice on where I should start in order to understand how I can achieve what I want. 

Thank you!

 

Hello,

I installed some java application (search "eTrader instalacja") but I can't get web traffic with Fiddler. Is is possible with Fiddler?

Hi!

I'm new to Fiddler, I had some success, but there is also an unsolved problem. My setup is:
- An appliance with an integrated webserver. (This appliance is accessible via HTTP only)
- A PC with Fiddler (used as a reverse proxy)
- Another PC with a Browser
All 3 components are in the same network.

I want to use Fiddler for 2 tasks:
- First task is to edit the webpage of the appliance on the fly, I need to remove some content. This works fine, I managed to edit the page with FiddlerScrip. On the PC with the browser I can see the changed webpage.
- Second task: For later use there is a requirement, that this changed webpage is accessible via HTTPS. I tried a lot of settings in Fiddler, but without success. I can't even see any reaction in Fiddlers Session window when I try to access the changed webpage via HTTPS. I assume that the ports are correct, because it works with HTML. Is there a way to solve this problem?

regards
Gerhard

I've been using Fiddler for years, not really messed with the settings, it's just worked.

At the moment I cannot get it to show any local traffic, developing locally in VS2019 and using Chrome. I have no filters on. Is there any setting I should be looking at?

After updating v5.0.20204.45441, the connection from the phone via HTTPS was lost
Regenerating and reinstalling the certificate doesn't help.
Problem on both Android and iOS

I updated my Fiddler Web Debugger today 11/4/2020 and I am no longer able to open existing Fiddler captures (*/.saz files). When I double click on them nothing opens up in Fiddler. 

 

How can I downgrade my Fiddler to an older version?

When I install this locally on my machine I am prompted to login using a web browser. In the hospital environment I need to use this, there is not internet access. How can I then install the program?

Hello, am new to this tool. Am trying to learn how to set break points in other to modify requests and response. I have searched for nvideos, but the ones i have seen are from old version of fiddler with totally different ui. Can someone explain or point me to a video that can assist.

When I use Fiddler to debug my program with CONNECT proxy for mailserver:995 it not work. But I compiled Org.Mentalis.Proxy and it work fine. Why?

After Fiddler return "Connection: close" no more traffic by tunnel.
