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

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.

I was trying to debug webpack generated application and webpack generates big JSON file called app.map. I was getting this error:

Source map error: SyntaxError: JSON.parse: bad control character in string literal at line 1 column 790260 of the JSON data
Resource URL: https://test.sceal.dev/js/app.bundle.js
Source Map URL: app.map[Learn More]

I was trying everything and nothing worked until I found out that if I disable fiddler and add test.sceal.dev in hosts it works. So JSON file is somehow modified by fiddler which makes it unusable. It should never actually modify the request unless I tell it to.

Am I missing something simple or is this really a bug?

I am testing some forms that are sent via POST multipart/form-data request to a server. I am using the Inspectors/WebForms tab and can see the form data however some of the Names have very long Values content. In particular I have one Value that is 4 paragraphs or 350 words. I want to be able to scroll down to read the data but it scrolls right to the end. There's like a dead zone where scrolling doesn't work.

I have attached an animated GIF demonstrating the issue. Note Fiddler's WebForms says multipart/form-data is not fully supported, and so this issue may have to do with that.

The download form lists United Arab Emirates, United Kingdom and Uruguay. After that is USA but initially I didn't see it, I stopped clicking at Uruguay. I suggest changing USA to United States

The current configuration value is nonsensical. I installed Fiddler in a VM to confirm it is not specific to my system. Screenshot attached.

I manually set Fiddler as the system proxy. When I tried to use Fiddler as a proxy it looped and made repeated connections to itself opening hundreds of connections. I realized what happened is since I have the Fiddler gateway set to use the system proxy and I set the system proxy manually (rather than use 'Capture Traffic' in Fiddler) it didn't realize it was connecting to itself.

This may be more of a corner case but I think if use gateway is enabled then you could check that against Fiddler and see if it's the same thing, and if it is then ignore it or warn the user.

I enabled Automatic Breakpoints > Before Requests but there are some arbitrary background URLs I'm just not interested in stopping, like for example after I enabled it there were like 8 requests to http://detectportal.firefox.com/success.txt. I would have preferred to select all those sessions and then 'Run to completion' for all of them in one fell swoop but there doesn't seem to be a way to do that. Instead it seems I can only initiate an action per session. There is 'Abort Session' but that just causes the browser to retry the requests which creates more sessions.

There is no option to disable hotkey (CTRL+ALT+F default) in Tools->Options General tab. Also when I leaving hotkey field empty, changes are lost after clicking OK.

In my line of work (security research), WebSockets are becoming increasingly common as a way to mask malicious activity. Fiddler does allow you to view a WebSocket and display the blobs exchanged. However, I have ran into some issues when the data is compressed and there doesn't seem to be native support for decompression. A workaround was suggested here: https://fiddler.ideas.aha.io/ideas/FID-I-103

More generally, it would be a great feature to be able to replay a WebSocket in 'offline mode', similarly to how you can replay HTTP/S Sessions via AutoResponder.

I would like to send a string to TextWizard and view it as a JSON tree, just like in the JSON inspector.

Like the JSON and XML tabs, there should be a Protobuf tab that offers to decode protobuf requests and responses.

I'm using v5.0.20181.13826 for .NET 4.6.1.  I just upgraded today.  I have a 4k display running at 3840 x 2160.  I have the font scaling set to 200%.  The previous version of Fiddler worked with these settings.  I accepted the update when prompted today, but the Fiddler UI is no longer scaling the font.  Many of the menus are inaccessible or unusable.

I set my resolution to 1920 x 1080 with no scaling and the Fiddler UI was accessible.  I was able to access the menus and set the Fiddler font to 16, and returned to my regular 4k display settings.  Most of Fiddler was readable under this setting, but several areas don't appear to acknowledge this change.  Screen shots attached.

I updated Fiddler this morning, and now clicking on my archived traces in Windows explorer no longer opens up the traces in FIddler.

After the latest update (v5.0.20181.13826) I keep getting out-of-memory exceptions. Sometimes it takes 10 minutes for it to happen, sometimes over an hour.

I just have Fidder running and I have these options checked:

* Catpure HTTPS CONNECTs

* Decrypt HTTPS traffic

* Ignore server certificate errors

This error was not happening before, only since the update.
