While inspecting requests where Content-Length > 3000, only 3000 characters of the request body gets displayed in both Raw and Text views. When I copy the whole contents of the selectable area (CMD + A, CMD + C) and paste it into a text editor, it seems like there is a 'View full request...' text somewhere which does not show up. I remember this button from previous versions. 

OS : macOS Mojave Version 10.14.6

MacOs, Fiddler Everywhere 10, Cisco AnyConnect.

Here's the workflow...

In the morning, Cisco VPN isn't connected.  All traffic is blocked by design.  Attempt to start Fiddler Everywhere.  WON'T START because it can't login.  What is this new requirement to login?  If I don't start Fiddler before the VPN, no traffic ever logs.  If i don't start the VPN, Fiddler won't start.  A bit of a cartch-22, ya think?

Somehow I bypass the VPN (Don't tell corp security) and get logged-in.  Fiddler is up.  Start the VPN. Get some work done.  Shiny new UI!  Still can't drag-drop from inspector to composer?  Damn.

At some point the Fiddler login EXPIRES.  Why does it expire?  What do I even need a login for?  At this point ALL TRAFFIC fails, since Fiddler was the system proxy.  All work stops.  Now I need to stop Fiddler, Stop the VPN, attempt to start Fiddler again....oh wait, can't login because the VPN is down...  here we go again.

This is all a serious waste of time.  I can see registering Fiddler so you know who your users are.  What's with the REQUIREMENT to have a login, and why does it expire?  It kinda makes Fiddler useless.

Please remove the requirement to login to an account before being able to use Fiddler Everywhere.

 

Thanks,

Sean

I'm unable to connect to "gateway.icloud.com" when Fiddler is open and decrypting HTTPS traffic.

This is Fiddler Everywhere 0.10.0 on macOS 10.15.5.

To reproduce:

Open Fiddler and make sure it's decrypting HTTPS traffic.

Open any browser and go to https://gateway.icloud.com/

Expected result: Page loads (it's blank. This is normal.)

What actually happens: fiddler.network.https> HTTPS handshake to gateway.icloud.com (for #820) failed. System.Security.Authentication.AuthenticationException The remote certificate is invalid according to the validation procedure.

 

Same thing happens on https://configuration.apple.com/

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

REQUEST

CONNECT 192.168.5.7:5000 HTTP/1.1
Host: 192.168.5.7:5000

RESPONSE

HTTP/1.1 200 Connection Established
FiddlerGateway: Direct
StartTime: 16:12:05.141
Connection: close

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 :)

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

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

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

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!

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.

But it don't have such options. 

I am not able to open few sites like  https://www.zillow.com/

Error:

An error occurred during a connection to www.zillow.com. PR_END_OF_FILE_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.

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 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.

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:
