I fire up Fiddler Everywhere on my Mac. Generally, it appears to do nothing.

In further detail, "Stream" and "Decode" can be toggled, but otherwise do nothing. The connections icon has a hover-over describing my host and states I have a network connection. The help icon goes to the very limited documentation via browser. The settings icon pops open the settings dialog, which does appear to save changes, but not impact the "nothing" being done by the application. The capture button and inspectors button appear to do nothing. The main viewing area states "No records available." The area to the right of the main area states "Please, select a single Web Session to inspect." And that is it.

Either I'm doing (or not doing) something dumb, or it just isn't working for me. Any help would be appreciated :)

Mac specs: High Sierra 10.13.6, 2.6GHz i7, 16 GB memory

Fiddler Everywhere won't even open on my ubuntu 19.04. I can see the logo-loading banner, and then nothing.

Sometimes when I close Fiddler Everywhere, the process Fiddler.WebUi stays alive.

When I try opening a second Fiddler Everywhere it can't bind on 8886 and I have to force quit (kill -9) the process before re-opening Fiddler.

I'm running on an Ubuntu 18.04 server. using VNC via gdm3 (gnome) display manager.

The first time I tried to run progress-telerik-fiddler.AppImage, it brought up a dialog asking if I wanted to integrate with VNC and install a desktop icon, to which I answered yes.

The window then closed, and each time I try to run progress-telerik-fiddler.AppImage again, nothing at all happens, as follows:

wxr-xr-x 1 root root 113958410 Mar 25 14:15 progress-telerik-fiddler.AppImage
root@cupertino:/nethome/osmolyar/fiddler#

There is no desktop icon, log, or anything.

Describe the bug
When the location of the Windows Desktop is changed (e.g. like described here), the functionality for exporting the root certificate is not working.

To Reproduce
Steps to reproduce the behavior:

  1. Change the location of the Desktop on Windows OS
  2. Run Fidder Everywhere, ensure that Setting -> HTTPS -> Decrypt HTTPS traffic is checked
  3. Press Settings -> HTTPS -> Decrypt HTTPS traffic -> Export root certificate to Desktop
  4. Error message is shown in a tooltip:

Could not find a part of the path 'C:\Users<username>\Desktop\FiddlerRootCertificate.crt'.

Expected behavior
The certificate is exported.

Desktop (please complete the following information):

  • OS: Windows 10

Scheduled for FiddlerCore Release

Hi there,

I've successfully setup fiddler-everywhere 0.4.0 and am able to sniff traffic to various websites on my linux (Ubuntu 18.04) laptop. However some https sites are not working - fiddler-everywhere severs the connection at the SSL handshake phase. These same sites work in the windows version of Fiddler (v 5.0.20192.25091 - built 04 June 2019) however.

What is the status of the SSL support in fiddler-everywhere vs windows Fiddler?

Example site that fails over https:

Fiddler can't connect to domains with 3 consecutive hyphens.

This error occurs:

fiddler.network.https> HTTPS handshake to r1---sn-ab5szn7e.googlevideo.com (for #793) failed. System.ArgumentException Decoded string is not a valid IDN name.
Parameter name: unicode

 

To reproduce:

Start Fiddler Everywhere (at least on Mac), make sure HTTPS decryption is enabled.

Go to www.youtube.com and try to watch a video.

The aforementioned error will occur in Fiddler.

howdy,

I've downloaded the latest 0.4.0 Fiddler Everywhere. When I run it I get an error - "A JavaScript error occurred in the main process". This occurs every time I launch the app. However it appears to run normally after I dismiss the error dialog.

I'm running Ubuntu 18.0.4:

```

lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic

```

Simple as that: fiddler everywhere does not capture traffic to localhost, 172.0.0.1 AND when you insert your local address, it captures your request only to return that "

[Fiddler] DNS Lookup for "www.192.168.0.18" failed. System.Net.Internals.SocketExceptionFactory+ExtendedSocketException Device not configured

"...

 

MAC OSX, using safari.

Other address are captured as expected

I installed Fiddler Everywhere on Fedora 31. Clicking "View full response" for any response opens a pop-up window which is reasonably sized, but the content of which is a scrollable area about one line high at the top of the window and there is no obvious way to expand it to see more than one line of the response. Screenshot attached.

Because it cannot be opened on my macOS 10.10.5. The application just flashed and closed as I tried to open it.

If you go to Composer and compose a request, if you switch back to inspector for whatever reason (fetch some info for exemple) the composer resets to an empty state!

Im using MacOS Sierra 10.12.5

 

2 BIG Issues are present.

First of all, I don't have an INTERNET connection any more after closing FIDDLER it has to be always running!

Second issue Fiddler is working properly ONLY on the first Start. If  closing it and opening it again it's not working at all.

FIX this ASAP

 

very very critical
