Since more and more websites enforce you to use tls 1.2 (and don't support tls 1.0 any more), I suggest that the list of protocols is automatically extended with tls1.2 by a next fiddler update - or at least there should be a single-time question box with Yes-No-Cancel to extend it.

Also see reference at https://www.telerik.com/forums/some-https-sites-are-unaccessible-when-using-fiddler

Hi,

I'm developing an application with Angular using Windows Authentication.

I tend to have Fiddler running all the time as it provides the authentication (using the Fiddler Automatically Authenticate flag).

As I have it running continuously the request pane gets quite large and the memory footprint increases as a result.  This is fine, and just the nature of the beast.

Periodically I clear the request pane out with CTRL+X but I have to maximize the Fiddler window first.

It would be really helpful if there was an additional option to clear the request pane from the menu on the system tray icon (please see attached).

Many thanks, and keep up the good work.  Cracking tool.

Franz.

执行“bpu xxx”请求断点后,AutoTamperRequestBefore(Session oSession)方法里oSession.oFlags.ContainsKey("x-breakrequest")=false。

但是执行“bpa xxx”响应断点后,AutoTamperResponseBefore(Session oSession)方法里oSession.oFlags.ContainsKey("x-breakresponse")=true。

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.

please add comments into a fiddler AutoResponder. And maybe hierarchy view for i can  create folders and create responses inside folders (for grouping). With group switch on|off.

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. :)

Hi,
Hi I am using Progress Telerik Fiddler Web Debugger version v5.0.20182.28034 for .NET 4.5 and I am unable to capture Https service wherein I can easily capture the HTTP traffic. The application for which I am capturing traffic is an ASP Dot net Core web application having version ASP.NET and Web Tools 2017 version 15.9.1 Microsoft Visual studio Enterprise 2017. I am facing issues in capturing Https traffic in spite of installing the root certificate and changing the system proxy for each protocol (HTTP, HTTPS, FTP) settings to 127.0.0.1:8888. Kindly help me with this.

Lots of development software has dark themes because it is less stress on your eyes and looks cool.

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.

Thanks for the note! P3P is now pretty much defunct (Windows 10 dropped it).

The redirector can be retargeted to the URL: https://web.archive.org/web/20080901012040/https://msdn.microsoft.com/en-us/library/ms537343.aspx#unsatisfactory_cookies

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?

In the black QuickExec box below the Web Sessions list, type:

prefs set fiddler.ui.rules.keeponly 123450

and hit Enter.

As a bug fix, Telerik should consider subscribing to changes in this value so that the toolbar UI updates with the "123450" number without restarting the tool.

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.
