[himyjan]

Configure Fiddler Classic:

Open Fiddler Classic.

Go to Tools > Options > HTTPS and check the box for "Capture HTTPS CONNECTs" and "Decrypt HTTPS traffic".

Click on "Actions" and select "Trust Root Certificate". Follow the prompts to install the Fiddler root certificate.

Click on "Actions" and select "Export Root Certificate to Desktop".

Set Up Zen Browser to Use Fiddler:

Open Zen Browser.

Go to the browser settings and find the security settings. Certificates - View Certificates - Import - choose Root Certificate export by fidler classic on desktop.

Go to the browser settings and find the network or proxy settings.

Set the proxy server to 127.0.0.1 and the port to 8888 (the default port used by Fiddler).
or
Set the proxy server to /Documents/Fiddler2/Scripts/BrowserPAC.js .

These steps don't work.

Hey there, @himyjan! I'm Dosu, here to help you with any bugs, questions, or contributions. Let's tackle this together!

To set up Fiddler Classic to capture requests and responses in Zen Browser, follow these steps:

1. Configure Fiddler Classic:

   • Open Fiddler Classic.
   • Go to Tools > Options > HTTPS and check the boxes for "Capture HTTPS CONNECTs" and "Decrypt HTTPS traffic".
   • Check the box for "Export Root Certificate to Desktop".
   • Click on "Actions" and select "Trust Root Certificate". Follow the prompts to install the Fiddler root certificate.

2. Set Up Zen Browser to Use Fiddler:

   • Open Zen Browser.
   • Go to Settings -> General -> Network Settings.
   • Select 'Use system proxy settings' if you want Zen Browser to use the system's proxy configuration, which should be set to Fiddler's proxy (127.0.0.1:8888) ^[1].
   • Alternatively, if you want to use a manual proxy configuration, you might need to set the proxy server to 127.0.0.1 and the port to 8888 directly in the Zen Browser's network settings, though specific steps for manual configuration weren't found in the repository.

3. Ensure Compatibility:

   • Make sure that the Fiddler root certificate is properly installed and trusted by Zen Browser. Zen Browser enforces HTTPS-only mode, which could interfere with Fiddler's ability to intercept HTTPS traffic unless the certificate is trusted ^[2].

If these steps don't work, double-check that the Fiddler root certificate is correctly installed and that Zen Browser is configured to trust it. Additionally, ensure that no other proxy settings are conflicting with Fiddler's configuration.
