"Fiddler everywhere" has animations.
I hate animations

How can i turn off animations?

I am developing a Chrome extension that activates a proxy. When I enable the VPN and reload the page, the following steps should occur:

1. The Chrome browser makes a request to the proxy.
2. The proxy sends a response with a 407 code.
3. Chrome should call chrome.webRequest.onAuthRequired and provide credentials to the proxy.

However, I don't see any browser interactions with the proxy server.

Is it possible to observe the interaction between Chrome and the proxy using Fiddler?

Is it possible with Fiddler Core to completely replace a response like its possible with Fiddler Classic to do in the "RAW" section if you put a breakpoint before the Response?

Thanks

I have a library that I'm testing out and the .Net Framework 4.6.2 project logs just fine with the normal app.config values.  When I set up the same project using .Net 6/7 I can't seem to get it to capture any packets.

I run netsh command under an elevated privilege command prompt before starting fiddler and then I run the debug mode in VS 2022 and see no entries come across fiddler.  

C:\WINDOWS\system32>netsh winhttp set proxy 127.0.0.1:8888

Current WinHTTP proxy settings:

    Proxy Server(s) :  127.0.0.1:8888
    Bypass List     :  (none)

The only way I can get it to log anything is to enable "Act as a system proxy on startup".  This isn't too practical as then I'm seeing all traffic, which is a lot.

The request is to an https-enabled site.

Is there something I need to do differently in this case?

All of the articles I have read points to this as the correct direction, but they are all 2019 or older.

 

 

Good afternoon!
Someone had a problem that you couldn't connect the Fiedler Everywere to a mobile device. Although the port and IP were entered correctly, but the link to download the certificate does not open. It says there is no internet connection. We tried to download and install the certificate separately, but still feedler does not see the android device

Hello.My Fiddler Classic Unable to capture traffic from Windows store.can you help me？

Hello,

I have successfully setup Fiddler Everywhere on my iMac as proxy, installed certificate and can watch traffic from my iPhone to HTTPS-sites using Chrome or Safari. Great!

But I would like to inspect traffic of other apps – like Find My – to Apple's servers. The app says "Find My not available, check network connection". It seems that the requests are blocked because the CRT is not valid for app traffic, just for browsers?!

Please advise, any help is greatly appeciated.

Hi, is it possible to only decrypt some HTTPS requests?
I only need to decrypt some specific, and since using

.DecryptSSL()

Will decrypt all HTTPS traffic, which is what I don't want. I only need to decrypt on specific URLs.
I found this example: https://docs.telerik.com/fiddlercore/basic-usage/capture-https-traffic#fiddlerapplicationbeforeresponse
But it looks to be for the actual Fiddler Application, not for the Core version, so I'm not sure if it will work, will the <session>.uriContains even work if DecryptSSL is not enabled, will it even find the sessions?

Thanks

I need to make a change to the text of a file that is large and if I do it the normal way this change doesn't happen, I think I don't have time to edit the response and that's why it loads without changing. Because in small files it replaces the normal load on the page with the modified response. Is there any way to get around this? Thanks.
