Hi 

I want to ask that when will be Fiddler Everywhere with all its webinar demo functionalities (new tabs for session view, filters, comments, auto responder, etc) will be launched

Currently i can't prefer using this version 5, because there are many functionalities of version 4 that are missing in it

I recently installed Fiddler Everywhere for MacOS from the product page https://www.telerik.com/fiddler-everywhere.

However after install I noticed it doesn't have half of the features that all the screenshots and documentation are featuring. Attached is a screenshot of the features I see when inspecting a request to CNN. No Auto Responder features, and no Web Sessions toolbar with filtering. Definitely doesn't match screenshots seen on the product page and documentation.

Is this expected? If so, this essentially makes Fiddler Everywhere for MacOS a glorified Network Inspect panel.

I am also having problems using the "Capture" button as seen in other threads and cannot make it work with restarts, reinstalls, starting in sudo, etc.

Any help appreciated as Fiddler is unusable in this featureless state.

If I activate fiddler, all my HTTPS requests start to fail...

     I tried logging into my Telerik account using the latest FireFox browser and there are a boatload of error messages in the developer's console. I could not do it. I had to go back to Chrome to login to this website.

Also, the latest version of Fiddler which I downloaded and installed yesterday will correctly capture my Intranet Chrome traffic but none of my Intranet FireFox traffic. Where is the support for the FireFox web browser?

I'm not sure how to describe this with any detail.  I have a JavaScript app.  It works fine without Fiddler running.  When I run Fiddler and enable capturing and decrypting of HTTPS, I get JavaScript errors when running the app.  All the other HTTPS stuff I've tried works fine.  (If I turn off HTTPS decrypting, the JavaScript app works too.  So it's something related to HTTPS decrypting.

I tried another product called Charles, and the JavaScript app works fine and Charles captures and decrypts all HTTPS traffic from this JavaScript app just fine.

But I'd rather use Fiddler.  But I can't figure out what the issue might be with Fiddler HTTPS decrypting.

I have already reset the Fiddler certs several times with no change.  Again, all other HTTPS works and decrypts correctly.

Hello Telerik team,
Thanks for Fiddler, it is a powerful tool for testing. I am using Fiddler V5.0.20202.18 for NET 4 on Windows 7.

I am sniffing and capturing HTTPS traffic generated by selenium + chromedriver on YouTube. For testing purposes, I export each test as a HAR file to examine its content.

My problem is that for all exported HAR files, the query string section is empty ("queryString": [],) . Instead if I generate the HAR file using devtool, I get those values.

Can you give me some guide on how I can get this content using Fiddler.

I would greatly appreciate any help,

Hi, we're trying Fiddler everywhere on OSX Mojave, as a replacement to Charles, and it seemed to work when first installed as I got the password prompt, but upon relaunch it now no longer prompts for a password. Clicking the 'Capture button also does nothing.

Any ideas?

Thanks

Have recently jumped from v2.3 to v5 and am having issues with a 502 error, "Gateway Connection Failed". This failure seems to be occurring randomly. For example, I can start capturing web traffic just fine, and in this case, I'm using Fiddler to ensure eLearning courses are sending a heartbeat/keep-alive to our Learning Management System.

The keep-alive occurs every minute. I'm experiencing the 502 error following one or more successful keep-alive POST events.

The response header specifically states:

502 Fiddler - Gateway Connection Failed

Cache-Control: no-cache, must-revalidate

[Fiddler] The connection to the upstream proxy/gateway failed. Closing Fiddler, changing your system proxy settings, and restarting Fiddler may help. 
System.Exception Upstream Gateway refused requested CONNECT. 407

 

Can I utilize a FiddlerScript or AutoResponder to keep Fiddler authenticated to the proxy/gateway?

I've noticed recently - on multiple machines - that trying to install Fiddler defaults to an install path as the one depicted below. The same outcome is observed regardless if running setup as a local non-admin user, starting setup as a local non-admin user but running as administrator or simply logging in as an administrator account and starting setup. Yet Fiddler is successfully installed and runs just fine.
One of the other outcomes is that using the Start button to start Fiddler by simply typing its name no longer works - regardless if installing to the default path (present in the picture) or manually changing the install path to Program Files\Fiddler. In the first case that would make sense up to a point at least, since Indexing doesn't look in AppData by default, but not sure why it fails to work in the second case.

The latest attempt to install - and the same result observed as above - was using the latest version available today.

Hey all

I am new to Fiddler, but we are in a position where our current ERP (Dynamics AX 2009) is too old and does not support TLS1.2 (its built on .Net 3.5), therefore pretty much all REST calls do not function. Fiddler came up as an option to be able to override SSL protocols to TLS1.2--which in my proof of concept (installed locally to dev box) is working fine.

However I am a bit confused on how I can actually implement this in a "production-ready" manner as all the calls will come from individual client machines on our network running the AX thick-client (its a standard client/server architecture), so I would need to put this in place somehow to target/override/log only REST calls from this application to specifics hosts (I have this working via FiddlerScript) for any calls coming from our internal network. We would need all other traffic to not be impacted.

I'd prefer not to install Fiddler on every client machine, so does it make sense to stand it up as a proxy server between clients and firewall? Is there a better way?

Thanks
