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

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.

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

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:

• https://www.absa.co.za

Example site that works over https:

• https://www.fnb.co.za

Fiddler captures for absa.co.za

fiddler.network.https> HTTPS handshake to www.absa.co.za (for #329) failed. System.IO.IOException Unable to read data from the transport connection: Connection reset by peer. < Connection reset by peer

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.

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 search use Socks5 and received answers:

Hi,

Fiddler supports SOCKS4a version. If you are trying to use another SOCKS version, this might be the reason why it is not working.

Could you please, elaborate on the error you receive.

He advised me to create a new request!

Will what I want to be done?

Thanks!
