    Well, the title says it all. It is working correctly, and able to capture traffics and view them. But if the option to "Capture Traffic" is disabled (e.g. via F12 or File menu), Fiddler still captures traffic as usual, as if the option is enabled. The status bar correctly shows the capturing state.

    Running Fiddler Beta v4.6.20171.26113 (Built: Monday, June 12, 2017) on Mono 64 bit on Ubuntu 16.04 AMD64.

    Sorry for the late reply. I tried to reproduce your problem but I did not observe the problem you mention. However, in the near future we are going to stop the updates of Fiddler for Mono, in order to concentrate on the development of FiddlerCore for .NET Standard and Fiddler Orchestra which will be a multi-platform application and eventually will replace the current Windows Forms based Fiddler. You can read more about it in this blog post.

    Until then, as a workaround I can offer you to modify the "attachWithGnome.script" if needed. It should be in the same directory with the Fiddler.exe. When Fiddler attaches or detaches (which means that it changes the gnome proxy settings to point to or to point back to whatever they were pointing before Fiddler modified them), it calls the "attachWithGnome.script" and passes the "proxyInfo.conf" file as an argument, which it creates on the fly. In the "proxyInfo.conf" Fiddler writes what should be the proxies for the following protocols in this order: http, https, ftp, socks

    However, if the application which you are debugging does not respect the new gnome proxy settings it will continue to send the requests to where it was sending them originally. In this case there is not much you can do except to change the proxy settings of the application in question manually or in the script file.

    I hope that this information is useful to you!
