Scheduled for Fiddler for Windows vNext

Describe the bug
"Get Started" tab resizes badly when the font size is increased, making headings like "Start", "Recent" invisible or with vertically arranged letters.

To Reproduce
Steps to reproduce the behavior:

  1. Change font size to 14 from Tools -> Options -> Appearance -> Font Size
  2. Limit the space available for the tabs by moving the vertical splitter to the right
  3. The text in the headings starts to layout vertically

Expected behavior
Get Started should look good on all available font sizes and Windows scaling settings.

Scheduled for Fiddler for Windows vNext

I'm using Fiddler [Oct-03-19] v5.0.20194.41348 on Windows 7 Enterprise. The AutoResponder panel has changed from older versions and no longer displays properly if the size is narrow. For example in the attached screenshot you can see no scrollbars or dropdown. They seem to have a minimum size of 850px right now. That is way too wide. I find it very difficult to use Fiddler when the panel is too wide because then I can't see the connection entries easily. The size in the screenshot is what I normally use the panel at and it works fine in older versions.

As a workaround I reverted to older version Fiddler [Jun-04-19] v5.0.20192.25091. Also I was left with a bunch of errant StringToMatch[xx] entries, not sure what that's about.

I recently reported a bug and I attached the wrong file. Fortunately it wasn't a sensitive file but I realized there is no way to edit my posts or attachments in this tracker. Ideally users should have the right to modify their own posts and attachments.

I'm using Fiddler [Oct-03-19] v5.0.20194.41348 on Windows 7 Enterprise. There's no way to disable the 'Get Started' panel on startup. 'Show on startup' is not checked but it still shows. Also it doesn't look very good. Also it downloads javascript and other stuff via http unencrypted from fiddler.com, and I'd like to stop that.

Once a program has been "Filter now"ed via the context menu, if that filter is later deleted from down bottom, that program can no longer be "Filter Now"ed again; nothing happens.

It's as if program filtering is only given one opportunity to be "Filter Now"ed. Once that's happened, even if they filter gets deleted, the program isn't given another opportunity to be Filter Now'ed.

Would it be possible to update the History section of the Composer so that the urls shown aren't cut off because of the column width? Resizing it is also a chore because first you have to resize the entire section and then the column.

Currently, in Fiddler, when I'm creating a new response in AutoResponder > Create new response... when I choose "Generate file", in order to save created response, by default it is saved on Desktop. Is it possible to add setting in which user can set folder path for generated responses?

The BCCertMaker exposes a !dumpcerts command that creates certificates on the desktop. Unfortunately, the DumpCertstoDesktop function does not name certificates well, so a wildcard cert ("*.example.com") cannot be saved because "*" is not a legal filename character.

The function should replace all * in the cert names with e.g. "_" or "_wildcard_" before saving.

Hi!

Is there any way to disable underlining of URL in Raw Inspector tab? It is very annoying when you try to copy part of the request but in fact open the link in the browser instead.

It would be great to have an option in the textWizard to convert an epoch date to a human-readable date.

Like: 1530417600 to "GMT: Tuesday 13 August 2019 08:32:48"

 

It would be great to have 2 options:

- convert epoch time to human readable time (GMT timezone)

- convert epoch time to human readable time (Local timezone)

 

Thanks for creating one of the most useful tools ever!

Repro steps:

1. Inspect a websocket connections traffic

2. Expand the preview column so that the message body should show more than 65 characters.

3. Observe that even though the column is wide enough to support more than 65 characters, only 65 characters are displayed.

Issue:

Fiddler does not set up it's proxy server for the websocket protocol.  Applications looking at the global proxy settings are told by WebRequest.DefaultWebProxy.IsBypassed(Uri) that no proxy server should be used for the specified wss Uri.

 

Replication steps:

1. Have a .NET application that uses websockets and checks WebRequest.DefaultWebProxy.IsBypassed(Uri) to see if a proxy should be used for a wss Uri.

2. Try to use Fiddler to observe websocket traffic

 

Workaround:

After turning on fiddler, enable "Use the same proxy server for all protocols" in the Internet Options / Advanced Proxy settings screen.

Fiddler is a great tool & Composer an excellent feature of it.  I frequently have to reboot my dev. PC  for various reasons (actually it crashes a lot) and loosing my Composer URL history is a painful consequence.  Could the URL history be retained between invocations?  I use a set of about a dozen different endpoints frequentl, so a history size of 12-20 would likely be enough.

It would be even better if the last used request header and/or body and/or type (POST/GET/..) and/or Protocol (HTTP/1.1 etc.) for each URL could also be saved but perhaps that is asking too much.

 Bless you for making this tool.
