Using the Fiddler Jam browser extension, the end-user submits their logs in a self-service and secure way. To eliminate the concerns and risks associated with storing sensitive data, the submitted captured logs are focused on the specific browser tab only.

The core components of Fiddler Jam are the Fiddler Jam Chrome Extension, which enables end users (or extension users) to capture HTTP or HTTPS network issues and submit logs in a secure environment, and the Fiddler Jam Portal, which stores these logs in the cloud for support and developer teams (or portal users) to locally replicate and further analyze those issues.
The Chrome Extension is aimed at end users and helps them troubleshoot website issues, but instead of manually attaching network logs to an email or a support ticket, they can directly share these logs through the Chrome extension. The submitted logs are automatically and safely stored in the Fiddler Jam Portal cloud and are available for the Fiddler Jam Portal users to inspect and help resolve those issues.
The Fiddler Jam Chrome extension logs all HTTP, HTTPS and WebSocket traffic between the Chrome browser and the Internet, and enables users to capture network traffic from any application. Read more about the recording logs with the Fiddler Jam Chrome Extension...
The problem - Fiddler does not work with chrome. When I open any page on chrome, I get the error "Your connection is not private: Attackers might be trying to steal your information from website (for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID". FYI, I easily fixed a similar issue with firefox.
Firefox has its own certificate store so I assume you just installed the DO_NOT_TRUST... Fiddler root cert there and everything worked. Pretty much you should do the same with Windows certificate store in order for Chrome to work. So make sure you remove all the fiddler certificates you previously generated and regenerate.
Hi Alexander,
Yes seems like Fiddler hides chrome's traffic. I see this as the comment in the strike-trough font line.

0 - ? 0 chrome:12000 Hidden due to stealth-NewOrReusedClosedWithoutRequest. Hidden due to stealth-NewOrReusedClosedWithoutRequest.
We getting somewhere, I did a quick google search on "Hidden stealth-NewOrReusedClosedWithoutRequest". One person was able to solve this by disabling chrome extension so I went ahead and disable all my chrome extensions and restarted chrome. But that didn't solve my problem. May be you have better idea on what does this mean, and how to resolve it ?
Yes I originally enabled `Strict site isolation` experimental feature but I disabled it and went as far as to reinstall chrome, nothing helped. Never the less, your explaining of reason behind the 'hidden due to stealth' error gives me some idea. This weekend I will install some process monitors and try to trace what's going on. Thanks for all the help, appreciate it.
Cheers
An interesting side note: The Sight extension for Chrome doesn't work either! It worked on my old installation of Windows but not on this one. Is my Chrome installation just screwy? I've tried disabling certain other extensions but nothing seems to change.
Today I had the same problem. I am using a proxy server, and it looks like chrome wasn't able to verify the certificate via the proxy server. Because after getting a direct internet connection, it was working again. Now it keeps working even if I use the proxy again.
Because the problem seemed to persist across multiple devices, all on the same Chrome profile, it dawned on me it was the extension 'Allow-Control-Allow-Origin: *' as this was a common denominator. Once CORS had been turned off (didn't need to disable the plugin or anything) GitHub loads and works fine.
I was having to look at performance issue of Javascript today, so I downloaded the trusty fielder2 to help me. If you are like me, you will have heard of fiddler but may not have had reason/time to use it.
This can be interesting to see what calls your Chrome extensions are making all the time. Not only can you see they are making calls out to websites/services but you can see/inspect what data they are passing and what is being returned.
Recently I have used fiddler for performance testing. I used fiddler to look at what OData and WCF calls were being made from a form load in CRM and seeing the performance of these calls. I used fiddler to optimize slow calls and work out where I could combine/cache some Odata calls to reduce the number of them.
After install i instantly noticed some strange activity on facebook and instagram. I analyzed chrome traffic with Fiddler and found out that extension connects to useragentswitch.com/socket.io/xxxxx and starts liking pictures.
If this is your first time learning about Jam, here's a quick rundown. Users of your site can use a Chrome extension to share the full context of an issue, allowing your support team to analyze the data immediately. If needed, developers can reproduce and debug the issue using the Fiddler Everywhere debugging proxy. (If you'd like to learn more about Fiddler Jam basics, check out Rob Lauer's article.)
This page contains useful extensions for Fiddler. For best results, please ensure that you're running the latest version of Fiddler2.
You can develop your own extensions using the IFiddlerExtension interface.
The Gallery extension (50kb) displays thumbnails of all images found among the selected sessions.
Last Updated: Oct 3, 2011. Now includes a timed Slideshow mode and image effects. Click the Help link for details.
The AnyWHERE extension (40kb) allows you to trivially spoof the responses to browsers' GeoLocation webservice queries. Works with IE9, FF4, Chrome, and Opera. Full source is included. Note: You must enable HTTPS decryption for this tool to work.
The RulesTab extension is a lightweight way to tweak your Rules script directly within Fiddler2. This extension is not as powerful as the RulesTab2 extension above (no syntax highlighting or Intellisense), but it requires less memory.
This extension converts a captured request into the C#, VB.NET, or Python code necessary to issue that request: -extension-request-to-code. The code can be run directly from the extension. (Updated 12/16/2012)
Microsoft Web Capacity Analysis Tool (WCAT) is the tool of choice of the IIS team as well as the Windows Performance Team. This extension allows you to export scripts from Fiddler and run them in WCAT. Learn more...
tmccann thanks for the clarifications. Yeah the postman interceptor extension for chrome will only cover my https openid connected [oidc] secured web api call scenarios. Not sure if it would capture ajax or spa framework [ aurelia, angular, react+redux, vue ] app calls against oauth secured web api and likewise with non-browser based app. Thanks for link to relevant tracking issue.
This has me wondering if I should use postman https capture support that makes use of the openssl generated certificate pair and windows manual proxy configuration approach OR the chrome/edge browser postman interceptor extension + postman app interceptor bridge approach. Is there a document describing the pros/cons of each of these options especially on enterprise systems with msft or netskope or other web traffic steering and casb security agents in place?
As per the pros and cons of proxy vs interceptor, proxy supports much wider use cases in terms of capturing requests on remote devices (could be a mobile phone or a remote system) and can capture traffic beyond the chrome web browser. Also, we have introduced features in Proxy such as saving responses as well as grouping your traffic intelligently to create a more comprehensive collection that can be collaborated upon. Hence we recommend you use Proxy for capturing traffic.
Crafting a CSP from hand is isn't the easiest thing to do, it's easy to overlook something. That's why there are tools to automate this process. The one I used is a Fiddler extension to collect CSP rules. I start up Fiddler after I've installed the extension and I make sure the "Enable Rule Collection" option is checked on the "CSP Rule Collector" tab.
Unfortunately, at the moment, there seems to be a bug in Chrome that ignores this rule. A Chrome flag prevents it from being executed. The flag however cannot be found in the chrome://flags settings. (Just to be sure, be careful what you change in those flags settings.)
Update: Twitter user spazef0rze pointed out that the "bug" in Chrome is an experimental feature. He pointed out that I can activate it under: chrome://flags/#enable-experimental-web-platform-features
Chris: When I enter that URL, the word GeoForm comes up on the tab but the bars keep looping, with no page loading. I just tried turning off all extensions thinking it was my browser (though another person had the same problem). It still hangs. Same with trying from Configure App. And, as just noted, works fine in Incognito.
But as discussed in the introduction, in scenarios that could potentially make use of E2E, such as issues while executing Query As a Web Service (QaaWS), Live Office, or Dashboards when they leverage Web Services, as the SAP Client Plugin E2E only works with Internet Explorer (IE), the procedure falls short for these scenarios. By extension, the limitation also impacts web browsers the SAP Client Plugin does not support, such as Firefox and Chrome.
When the issue has been reproduced, collect the fiddler trace (always good as a reference point), as well as the Web Services traces (SBOPWebApp_ws) and the back-end trace (the BI logging directory) on the server and the BusinessTransaction.xml on the client (Please refer to the Concepts sub-section above and KBA 1861180 for reference to log gathering)
tl;dr
The Postman App was sending an Origin header to /_api/contextinfo and that was generating a 403 Forbidden. Using a fiddler rule I removed the Origin HTTP header and the call to /_api/contextinfo endpoint then worked.
