After Updating the Fiddle it shows this message and Fiddle Won;t Start.

how to Solve this issue or i have to uninstall and install it again ?

Starting Android N (7.0) and up, Google has chosen only to allow leaf certificates that expire within 39 months.
First mentioned for chrome in 2015: https://bugs.chromium.org/p/chromium/issues/detail?id=475745

Could you please consider either reducing the lifetime of the root CA to <39months AND / OR allow us to import our own CA like competitors already offer.

We like working with Fiddler but the inability to supply custom CAs easily and not adhering to the above requirement set by Google in Android 7.0 + forces us and many others to having to avoid using Fiddler.

I am using Fiddler to monitor some services I wrote.

I used File > Capture Traffic to stop it from capturing, but it's still capturing.

What's going on?

Hello Telerik, I've been trying to use your software "Fiddler" lately and I found it really difficult to use. Can you please help me glitch something called "rare skin" on a game called MovieStarPlanet? Thanks :)

Just got my fiddler updated to version v5.0.20181.13826 for .NET 4.6.1 and now the Font is very small to be read, also the menu is stripped in half.

How can I return to the previous version or fix this one?

System scaling is ignored. Main menu is 1/2 cut off (except for Tools, oddly).

Previous version was fine.

Any idea what I can do about this?

See attached showing the donked up menu and a properly scaled about box on top of an illegibly tiny (on UHD) main window.

 

 

This was the error message:

Granted the error message does give helpful stuff like: "Sound API only supports playing PCM wave files."

Which means the response was likely just incorrectly assumed to be a wave file.

I clicked the PLay button on the WebView becuase none of the other views are useful.

I would really just like to download a version of the file and then play it from another application but I do not know how in Fiddler and that would be the larger issue.

 

I installed Fiddler on Fedora 24. After running Fiddler for a while, Fiddler crashed suddenly with this error.

After this error, I can't see Fiddler Window and I found all the internet connection are lost. I can't connect internet page on Chrome browser even though the Fiddler and mono process . The workaround is launching Fiddler again and exit from the menu.

I've been working with fiddlercore to capture headers not raw packet data(which i don't need) now for more more info i shifted to windows form(c#) to windows service(c#). As i'm in learning process i'm facing some issue related to fiddlercore. 

Well the issue is i'm facing is not technical or programmatically  solvable. Any have any demo to how to work with fiddlercore in windows service because i just need some guide lines 

How can I "not load" the the binary of any requests? 
Sometimes I simply want to read the Content-Disposition parameters of file uploads. For example:
If I had uploaded a 10MB file it would have been pretty much impossible for me to get all the Content-Disposition parameters. Because as soon as you click on such a big request/response in raw mode, Fiddler freezes trying to load a huge part of the data into the GUI, but usually it stops after x KB and thus doesn't give me the content-disposition parameters below the binary part.
