Currently, Fiddler Everywhere just hard-fails on any invalid SSL certificate. More annoyingly, it doesn't explain why the certificate is invalid.


Fiddler Everywhere should:

1. Allow overriding a certificate error (possibly hide this behind an option)

2. Explain what caused a certificate error

I am unable to capture any traffic when connected to my company's VPN (Pulse). With so many people working from home these days, Fiddler Everywhere is positively useless without the ability to use it with a VPN. A few details about my setup:

* I am working on a Mac running Catalina 10.15.7.

* Fiddler Everywhere captures traffic just fine when I am not connected to the VPN, but as soon as I turn it on, no new traffic shows up. When I disconnect the VPN, I immediately see it capturing regular traffic again.

* I cannot connect to my VPN while running Fiddler Everywhere. My VPN Client just spins until it times out when trying to connect with Fiddler running.

* I tried following the instructions for working with Cisco VPN (even though I am using a different VPN) here: https://docs.telerik.com/fiddler-everywhere/knowledge-base/configure-vpn-with-fiddler, but it didn't work. I wasn't able to follow the instructions perfectly anyways, since I can't connect to my VPN while Fiddler is running. But I tried shutting down Fiddler after Step 4, and then restarting it after Step 5. It didn't work.

Please fix this problem! I really liked using Fiddler on Windows, and there really isn't another good comparable product out there for Macs that I have found!

I am trying to login to fiddler anywhere on Ubuntu.  But since the system is behind proxy, while logging into proxy, i get network error.

I have configured the proxy in env variables as well as network settings >proxy, but it does not work.

Please provide a way to configure the corporate proxy for fiddler everywhere before login

Fiddler for Windows allowed you to add custom columns to Web Sessions list. 

Fiddler Everywhere needs this option so I can add in a column to show the IP address of the server being connected to.

Can these methods be added into Fiddler Everywhere:

  1. https://docs.telerik.com/fiddler/knowledgebase/fiddlerscript/addcolumns
  2. https://docs.telerik.com/fiddler/Observe-Traffic/Tasks/ConfigureColumns

Colleagues, please add an essential feature of Fiddler Classic called Automatic breakpoints


I'm sure that a bunch of people will migrate to Fiddler Everywhere if you implement this

With Fiddler on Windows an imported HAR file would load into a new window

Current Fiddler Everywhere appends the HAR file into the current window you have open. 

For example, I see my HAR import and it gets appended into the "Live Traffic" session. It should import into a new window like the existing windows version does.

While navigating in recorded sessions, keyboard up/down buttons scrolls up and down. Expected user behavior is to navigate to previous and next the sessions.

I love the FiddlerScript feature. Will Fiddler Everywhere have this feature? Or maybe command-line feature?

Simple: you right click a request, a menu pops-up and you can click "Replay" that request. For extra points: Replay in sequence or parallel

I'm not 100% sure if this is a bug or it's a feature (of lack thereof) but it goes like this:

On regular fiddler, a great thing to do is to simply copy a raw request to the raw composer, change a param and re-issue it... Fiddler everywhere does not allow that! I have to write headers on a tab and the body on another and yet, there's a "Raw" tab.

The Raw tab unfortunately is not editable (read-only)... I believe that it should be editable

The last release of fiddler was on August 2019. You guys seem to given up on it... why don't you open source it, so we can improve and fix bugs?

Hey folks. There is a serious lack of guides/tutorials on using fiddler.  

So to set things up you have to use 5 year old stack posts, and if you're lucky things will work.  


This has been my biggest issue when it comes to incorporating Fiddler into my workflow. 


Right now I'm struggling with setting up a Root CA on Ubuntu (cos the cert is weird).


So yeah. Tl:dr Fiddler Everywhere needs guides and tutorials that are easy to follow and available for multiple OS's

It would be nice if I could right click on a header from a capture and quick add to the capture filter instead of coping and pasting.

Add the ability to use Fiddler Everywhere as a backend by recording, intercepting & modifying responses.

This is similar to the Fiddler's AutoResponder functionality.

Fiddler Everywhere   (How to set up my country's language, I saw PAK language pack file)
Last Updated: 13 May 2020 12:16 by ADMIN

Operating System: macOs Catalina 10.15.4

Step by step instructions on how to reproduce the problem:

  1. Connect to VPN (mine is Cisco AnyConnect).
  2. Open fiddler capture traffic.

You can also do the following to reproduce the problem:

  1. Open fiddler capture traffic.
  2. Connect to VPN (mine is Cisco AnyConnect).


Use case: I work remotely and connect to a VPN. In comparison, Charles Proxy can capture traffic when VPN is on. The comparison was to point out traffic is possible to be captured on VPN to counter any arguments.

Having used the original Fiddles for almost a decade. The new one looks great, but the UI scaling is way too big and spacious for actual production work.

We may have hundreds of requests in one test case and it's important that we see as many requests as possible on one screen so that we can get the whole picture how a service works (for example when reverse engineering something that's badly documented).

With the new UI it's only possible to see few dozen requests, so some kind of UI scaling is required. Also the inspector windows use way too much vertical space. It's really hard to see what's happening in a large request/response.


In my opinion the usability and productivity are more important than how sleek or modern the UI looks. Please prioritize the usability of the UI. Until then, I will be enjoying the classic Fiddler :)

In Fiddler on my windows machine I'm able to edit the customrules.cs file in order to tell Fiddler where to look for a cert. Having just switched to a Mac I'm eager to do the same with my install of Fiddler Everywhere but I can't find the file or any reference to it. Is this a missing feature or an error on my part?

I would like to be able to configure the following values via command line in the Mac version of Fiddler Everywhere:

In Preferences:

  • Decrypt HTTPS traffic (under HTTPS)
  • Fiddler listens on port: #### (under Connections)
  • Act as system proxy on startup (under Connections)
  • Manual Proxy configuration (under Gateway)

The best way that I've seen this implemented is in Chrome.

Chrome's settings are by default stored in a JSON file, but a Mac administrator can configure settings using MacOS's built-in preference system (either via the command `defaults write` or using a config profile) which will then enforce the settings.

In the meantime, if there's a text file I can edit, I'd love to do that.

Fiddler Everywhere cannot currently open any password-protected .saz archives saved from the Windows version of Fiddler.  Need to be able to open password-protected .saz archives and save captures as .saz archives with password protection.  Thanks in advance for any help on this.
