You should delete the routes from IE connection settings and any mods your application makes to the registry when the user clicks on the X in Fiddler. It seems like when you exit using File > Exit it does a "clean" exit. Please make this consistent.
When checking for updates I noticed that when I have 'offer upgrade to Beta versions' enabled, the response shows the latest version as 4.6.20171.14978 [03/22/2017]. I disabled checking for beta versions and it returned the latest released version ( 5.0.20181.14850 [03/20/2018] ). Not sure if this is intentional or a bug. Just thought I'd point it out.
Today, we can only choose one font and stick to it globally on app. Would be nice if the menus, lists, trees, etc. kept the Windows default font and only the inspectors, etc. have a custom font. In other words: I would like to use a cool monospaced font for input/output, inspection, etc. but a normal font for lists, menus, labels, etc.
Once I got Fiddler on the mac to run, I kept seeing the message in the Terminal that it couldn't find settings.txt file, once I created the settings.txt file I did get another message which I will include in another idea Here is the exact bash message: /Fiddler/settings.txt: No such file or directory iPhone Not sure if the iPhone piece is relevant or not.
The Fiddler 4 installer thinks there's something still installed in c:\Program Files (x86)\Fiddler2, but that folder no longer exists and the old version of Fiddler is no longer listed in "Programs and Features". Error message when I run the new version: "Machine-wide Progress Telerik Fiddler installation has been found at C:\Program Files (x86)\Fiddler2\ . Please, use that one or uninstall it before starting the per user Fiddler installation." The offending folder does not now exist. "c:\Program Files (x86)\Entity Framework Tools" exists. "c:\Program Files (x86)\Google" exists. There is nothing between them. They are adjacent in the directory listing. Resolution: 1. I uninstalled Fiddler 4. 2. I installed Fiddler2 (installer file version 184.108.40.206) from an old installer that, by luck, I happen not to have deleted. 3. I uninstalled Filddler2 manually. 4. I installed Fiddler 4 again. Now Filddler 4 runs. But if I hadn't still had the old installer lingering in my downloads folder, I would have been out of luck. Please fix.

Currently by listening to FiddlerApplication.OnWebSocketMessage it's possible to modify the incoming & outgoing messages but it's not possible to send independent direct messages in or out. Adding the ability to send direct messages will give more freedom on injecting custom messages in both directions, repeating server response messages etc. Currently if you need to inject an outgoing message you need to wait for the client to generate a message and only then intercept, modify and forward it. Sometimes the client may wait longer times to respond and a direct message mechanism would be quite useful to generate quicker responses.

I need help with inserting cookies through FiddlerScript. I have cookies like below which contains " inside cookie value, when I remove " from cookie value I stopped getting response from server. Now the real problem is FiddlerScript doesn't consider any cookie value outside " if I am correct. Pls help in finding some solution for me.

To be clear, you've paused a request via a request breakpoint, and you want to edit that request without using one of the higher level editors? Simply switch to the RAW request inspector tab and edit the request to taste, then click "Run to Completion" or "Break on Response".
The setting value(s) must be typed in directly. Default values are not shown in the about:config tab.
It's not entirely clear what sort of "History" are you talking about here-- most of these options are already available in Fiddler's Web Sessions list. If you're talking about the History panel on the Composer tab, you're better off just using a Fiddler Viewer instance and just drag/drop desired requests to the Composer.
I changed from to <client>; ssl3;tls1.1 ssl3;tls1.0 And now it WORKS. In this configuration Fidder is sending a Client Hello Version TLS 1.0 (ox0301) Handshake Protocol: Client Hello Version TLS 1.2 (ox0303) This works. Please add logging so it shows what exactly Fiddler is sending on the handshake. Evidently the user input for the HTTPS Protocols is a bit buggy / finicky. Please document what <client> does as well.
AutoResponder Rule Editor only shows the URL match field, and the "Test..." option. The combo to choose a pre-defined response and the Edit Response button don't show up (and the panel cannot be resized)! This seems to be new in v5.0.20181.14850, as it never occurred with older versions.
Can you please elaborate on what exactly you're trying to do and what exactly isn't working? You can toggle Fiddler as the system proxy by simply clicking the command on the File menu or by tapping the "Capturing" icon at the bottom-left corner of Fiddler's main window.
Downloads from the https://www.telerik.com/download/fiddler download page don't seem to have any problems.
In the Fiddler log I see this: 19:13:42:5608 [HTTPWarning] Header folding detected. Not all clients properly handle folded headers. I need to know what session that is from. I have thousands of sessions. If you could just add from session 1234 then I would know. Thanks v5.0.20181.14850 for .NET 4.6.1 Built: Tuesday, March 20, 2018
I recently tried to change the cert generator of Fiddler on a machine where there must have been some access control policy or something because I couldn't add a root certificate to the trusted root store and Fiddler couldn't create certificates. In Fiddler I saw this: 17:29:23:8243 DefaultCertMaker: GetRootCertificate() did not find the root in the Windows TrustStore. 17:29:23:8273 DefaultCertMaker: GetRootCertificate() did not find the root in the Windows TrustStore. 17:29:23:8293 /Fiddler.CertMaker> Invoking CertEnroll for Subject: CN=DO_NOT_TRUST_FiddlerRoot, O=DO_NOT_TRUST, OU=Created by http://www.fiddler2.com; Thread's ApartmentState: MTA 17:29:24:0083 !ERROR: Failed to generate Certificate using CertEnroll. System.Reflection.TargetInvocationException Exception has been thrown by the target of an invocation. < CertEnroll::CX509CertificateRequestCertificate::Encode: An internal error occurred. 0x80090020 (-2146893792) The blame is very likely on my end but Fiddler's behavior I think was troubling because it allowed HTTPS connections to continue without decrypting or intercepting the contents even though 'Decrypt HTTPS traffic' was checked. If the user has specified traffic interception but Fiddler is unable to do it then I think the connection should be stopped before the transfer can start. Also the error message box kept popping under my windows instead of on top which was annoying. A screenshot of it is attached. I installed the Bouncy Castle alt certmaker (fiddlercertmaker 20170915.exe) and either that or something else I did (?) worked because Fiddler is working now. v5.0.20181.14850 for .NET 4.6.1 Built: Tuesday, March 20, 2018
