Hi Team
I would like to know how I can add comment to captured calls via command line using ExecAction. This is for identification like start of login , start of some other transaction etc..
Tried to find references in CustomRules.js , no luck there.

Hello. I installed Fiddler 4 and now whenever I use NuGet, in Visual Studio 2019 or in other applications that use NuGet, no feeds work unless I open Fiddler 4. I thought that removing Fiddler 4 and the HTTPS certificate would fix the problem, but it didn't, so I reinstalled Fiddler 4 to be able to use NuGet.
I also had Fiddler Everywhere installed, but having it open or closed doesn't make NuGet work, only Fiddler 4 does.
Things I tried:
I'm at a loss here, I just want NuGet to work without having to open Fiddler. How can it still be broken even after removing Fiddler?
What else should I try?

Installing fiddler and and first start receive the error unable to create following file :
the file never gets created
I've check one drive permissions and I have full permissions. Any yes using OD4B
Is there a setting to change the location of the CustomMimeMappings.xml', I presume its one drive causing the problem
Thanks

I need to explore the traffic from one program.
The program makes something like a connection through the WebSockets.
Fiddler displays this:
Request Headers: `CONNECT 144.***:443 HTTP/1.0`
Response: `HTTP/1.0 200 Connection Established`
End empty body.
But httpanalyzer displays full information after that response, and that information continues flowing. Very likely like WebSockets (one connection and receive more answers).
And fiddler display zero traffic.
How can I explore such traffic through the fiddler?

On this project, for example, when I enter the yahoo.com site, I can change the response result of this site. However, when I want to change this page yahoo.com/fiddler_love and enter this page, I get 404 error result. 404 Error Response I cannot change the response value of the pages I receive. How can I change the response value of the pages that I get a 404 error, that is, nonexistent? For example, in the application I gave in the link above, I can change the response value of the yahoo.com page. Because such a page exists, but yahoo.com/fiddler_love this page's response does not change.
Because there is no such page. In summary, how can I change the response value of this page? 404 How does the response value change regardless? Thanks <3

I've installed Fiddler Everywhere(1.6.0) about 2 weeks ago on my Windows 10 machine and it worked fine. Since about a week, I can't start it, if I open the exe file, nothing happens.
I tried reinstalling it, I've installed even 1.6.1, but I experience the same symptom. Please find the latest entries from AppData\Roaming\Fiddler Everywhere\Logs\electron.log file:
