Latest version of Fiddler (v0.10.0) and Android Emulator is not proxying the connections properly.
I have Fiddler Everywhere running and know it is working when I can send requests through Postman and see them show up in Fiddler properly.
However, if I set up the Android Emulator through Android Studio, and set the proxy to be Fiddler, connections do not fully reach the backend service I am sending requests to. All that shows up in Fiddler is
CONNECT 192.168.5.7:5000 HTTP/1.1
HTTP/1.1 200 Connection Established
The service is running on my local host machine (192.168.5.7) on port 5000.
If I close Fiddler and run charles-proxy, then set the Android Emulator to use that as the proxy, I see the full request, my service responds, and I see the response in Charles.
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 :)

Simple as that: fiddler everywhere does not capture traffic to localhost, 126.96.36.199 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

Other address are captured as expected

Bug 1: switching between Composer and Inspectors clear Composer fields
Start the program
Click Composer on the right side
Under Headers, fill something in
Click on Inspectors on the right side
Click Composer on the right side
The text under Headers is now resetted
Bug 2: POST body double new line delimiter and body data are formatted as headers
Start the program
Click Composer on the right side
Under Headers, fill in a POST header:
Under Body, fill in some POST data:
Click on Inspectors
Click on the result request
Check Headers or Raw, it says:
POST http://example.com HTTP/1.1
Notice the ending, it handles the POST data as parts of the header
1. Open Fiddler.
2. Open up a web browser and go to any page that is reasonably large (e.g. https://www.aol.com/)
3. In Fiddler, select the request (click Decode if necessary), then go to the "Raw" tab, scroll down, and click View full response.
Expected result: A decently large window opens with the response
What happens: The window only shows 1 line at a time. See attachment.

I tried to start app but every time nothing happens except short appearing a splash screen. Bellow detail from terminal:
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
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.
Steps to reproduce the behavior:
Could not find a part of the path 'C:\Users<username>\Desktop\FiddlerRootCertificate.crt'.
The certificate is exported.
Desktop (please complete the following information):
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:

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.
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.
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
