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.

Consider adding System.Core.dll to the default references list. This will allow easier usage of System.Linq in the scripts.

Tools > Options > Scripting has a new Language Dropdown.

It should be a DropDownList instead of a dropdown, otherwise, any character the user types causes a popup alert and the user can be left with a garbage value.

Further, there probably shouldn't be an explicit warning that a restart is required, as a great many options on the Options dialog require restart and showing this warning for only one of them may be misleading.

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.

It's huge, doesn't have anything to do with Fiddler besides being a Telerik product, and I have no interest in it after having used previous Telerik toolkits.

Chrome 57 won't accept certificate chains that contain SHA-1 within them, so we need to be sure that Fiddler/FiddlerCore default to SHA-256 everywhere. We also might consider whether we should detect that the user has old Fiddler-generated SHA-1 certificates cached and if so, clean those up and generate a fresh cert using SHA-256.

Should be "Automatically reload script when changed"

The handler for the "M" key in the AutoResponder needs to suppress the keypress. Right now, if you have a rule in the "If request matches" column that starts with "M" and you select a different rule, hit "M" to add a comment to it, then Windows automatically focuses the list item that starts with "M", then Fiddler invokes the "Add Comment" action on that rule instead of the one originally selected.

In autoresponder tab the rules could be grouped by project like the attachment . It may facilitate to users administrate your projects

I find myself applying the same filters again and again on each launch of Fiddler (I mean the filters listed below the list of requests).

I think it would be really great if you could allow the restoration of previously applied filters (e.g. by having a save/load filters option).

Also, allowing to filter out by "Request Method" would be great too.

Congratulations on this tool, by the way.

It is really great. :)

I had request with json body, after exporting to curl, looking at the batch file, i didn't see the body part of the request

It would be really great to be able to view requests and responses as a formatted json string.  Currently, you can show JSON, which uses some tree format, and you can show raw, which is just a flat hard to use string.

It would also be great to be able to format json inside the request composer so it can be easy to modify.

Add support for Socks5 + Socks Proxy w/ Authentication

Hi!

Is there any way to disable underlining of URL in Raw Inspector tab? It is very annoying when you try to copy part of the request but in fact open the link in the browser instead.

The error messages pops up on Windows 10 version 1703.  Fiddler installs and runs with not issues on Windows 10 version 1607.
