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

This is essentially dupe of FID-I-313.

Did you record your settings when this happened? Fiddler does, typically, reject such loops, unless it fails to recognize that the settings point to itself (e.g. your system is set to machinename:8888 and Fiddler is set to use 127.0.0.1:8888).

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.

True. You can just pick a hotkey so obscure that it'll never collide (e.g. CTRL+ALT+| or something).

Yup, there are two big missing pieces here:

1. Allow injection of messages on an active websocket connection, via FiddlerScript and the WebSocket Inspectors UI
2. Enable WebSocket playback from a SAZ file in the AutoResponder

FWIW, you can do Edit > Paste As Sessions and then just use the JSON inspector directly...

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

I'm seeing the exact same issue. I then added the -dpiAware switch to the shortcut which helped some but parts of the app are still displaying wonky. See screenshot.

I wasn't able to reproduce a problem with this on Windows 10.

On which version of Windows do you have this problem? Do the .SAZ files still show the gray/green crate icon? Does double-clicking the file start Fiddler, or do nothing at all?

In RegEdit, what do you see inside HKEY_CLASSES_ROOT\Fiddler.ArchiveZip\Shell\Open\command

https://groups.google.com/forum/#!forum/httpfiddler is the better place to discuss this, but the most likely explanation is that you're attempting to manipulate WinForms UI from a background (network) thread. You need to use a BeginInvoke API to do so with thread-safety.

I've confirmed that the latest version of Fiddler is locked to 32bit, which causes this problem.

Once I had gotten Fiddler to run (had to tell Mono to run in 32 bit mode) and I had re-created the settings.txt file, I received this error when trying to capture traffic:

Fiddler/FiddlerAttach.applescript:7:87: execution error: /bin/sh: USB,127.0.0.1,8888,on,127.0.0.1,8888,on,0,0,off,0,0,off: command not found (127)

Can't use my freshly installed Fiddler + mono 5.2 on Yosemite. As Eric suggested over at https://groups.google.com/forum/#!topic/httpfiddler/7cR_NHbx5PE I'm posting my similar crash data here:
