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

Add the ability to use Fiddler Everywhere as a backend by recording, intercepting & modifying responses.
This is similar to the Fiddler's AutoResponder functionality.

Platform: Linux.
Product: Progress Telerik Fiddler 0.5.0, downloaded today.

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
Select POST

Under Headers, fill in a POST header:

Host: example.com
User-Agent: test
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Language: en-US;q=0.7,en;q=0.3
Content-Type: application/x-www-form-urlencoded
Connection: keep-alive

Under Body, fill in some POST data:

data=1

Click Execute
Click on Inspectors
Click on the result request

Check Headers or Raw, it says:

POST http://example.com HTTP/1.1
Host: example.com
User-Agent: test
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Accept-Language: en-US;q=0.7,en;q=0.3
Content-Type: application/x-www-form-urlencoded
Connection: keep-alive
:
data=1:

Notice the ending, it handles the POST data as parts of the header

To Reproduce:

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.

Hi all,
I tried to start app but every time nothing happens except short appearing a splash screen. Bellow detail from terminal:

***************

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 :)

Thanks.

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

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.
