I get the following exception saying to quit or continue the application, if I continue capture does not begin.

Here's the content of the error:

See the end of this message for details on invoking

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Microsoft telemetry calls to v10.vortex-win.data.microsoft.com bypass the filters and add noise. If my filter says only show localhost, I don't expect to see calls to Microsoft.com.

Not sure if this is a recent change, but I use Microsoft Outlook and Skype, and both are having connectivity issues when Fiddler is running. Also Windows 10 apps seem to be unable to have an internet connection as well.

You know,jmx file can be used by jmeter. It's very useful, but fiddler cannot export the response ande request to .jmx.

So regretful.

Once I had gotten Fiddler to run (had to tell Mono to run in 32 bit mode) and I had re-created the settings.txt file, I received this error when trying to capture traffic:

Fiddler/FiddlerAttach.applescript:7:87: execution error: /bin/sh: USB,127.0.0.1,8888,on,127.0.0.1,8888,on,0,0,off,0,0,off: command not found (127)

When the PDFView Inspector is installed (v1.1.0.3, whose public override int GetOrder() method returns 500), the Response Inspectors are rendered out of order, such that the Headers/Transformer inspectors are not at the front of the list.

There are some Files, fiddler needs write privileges:

rm: cannot remove '/opt/fiddler/listeningProcess.txt': Permission denied
rm: cannot remove '/opt/fiddler/gsettings.txt': Permission denied
rm: cannot remove '/opt/fiddler/proxiesFromInterfaces.txt': Permission denied
...

If this file is stored with the exe file, it is not possible to install fiddler in /bin or /opt and run without root privileges.

I think it would be good to locate that file in the users home folder or in /tmp.

I'm using Fiddler v4.6.20173.38786 (Built: Friday, September 15, 2017). When I click on the Customize Rules menu entry there is a message box that says "Unable to load Fiddler for code-completion support". After I click OK to that the Fiddler script editor will open normally.

Please package Fiddler with Homebrew Cask (https://github.com/Homebrew/homebrew-cask) , or at lease permit them to distribute the binary. Currently they are concerned about distributing Fiddler (https://github.com/Homebrew/homebrew-cask/pull/41374) .

Fiddler swaps out the real proxy settings for localhost when in use. When you disconnect or close it, it restores the proxy settings. However, if the system crashes or power fails while Fiddler is in use, upon rebooting the real proxy settings are of course missing, they're still set to localhost. I would expect that if were to then run Fiddler, it would find those proxy settings again so that if I run Fiddler and close it again, my original proxy settings would be restored. Sadly this doesn't happen so in this scenario I have to manually set up my proxy settings again. Can this be implemented?

I want to set the maximum session count to keep. Add some option in the configuration like "Max sessions to keep" so I can choose it from the menu "Keep sessions". Right now maximum session count I can choose is 10000 but it's too small value for me.

Office365 capturing stops when access token expires, blocking office refresh token?

After 1 hour the access token expires and from that point on Outlook (office365) just starts getting 401 unauthorised responses and outlook stops working (don't get this when fiddler is not running). Other people on forum also saying they have seen the same issue.

I unchecked the "check for updates" box for a reason. It's just too much overhead and interrupts my productivity to have to stop and deal with an update before going and debugging the thing I'm working on. Even if the version is old, I'd rather just keep working than be interrupted.
