I accept your update and get to the install part and Windows 10 tells me that the update has an invalid certificate (or something).

The error messages pops up on Windows 10 version 1703.  Fiddler installs and runs with not issues on Windows 10 version 1607.

I find having Capture on when you start Fiddler a pain since almost always one of the first things I have to do is turn it off. I'd like the option to just have it off on startup.

Please remove popups that open when opening fiddler, for example the update prompt, and the survey prompt that showed up today.

Please honor the option to disable capture. I use fiddler to test API development and I never want it to capture any other traffic.  The configuration option to disable this doesn't work, please fix.

Repro:

1. Save a JPEG on your desktop as foo.Jpg

2. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header.

File extensions should be treated as case-insensitive when mapping to MIME types (Utilities::ContentTypeForFileExtension).

3. Rename a text file to foo.map

4. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header from the registry.

It looks like the registry may not be getting consulted properly; perhaps this was done with the introduction of CustomMimeMappings.xml which was presumably added to better support running on Mono/Linux, but Fiddler should still fall back to the Windows registry on Windows.

Not sure if this is a recent change, but I use Microsoft Outlook and Skype, and both are having connectivity issues when Fiddler is running. Also Windows 10 apps seem to be unable to have an internet connection as well.

Today, you have to write annoying code like:

if (((oSession.responseCode == 301) ||
   (oSession.responseCode == 302) ||
   (oSession.responseCode == 303) ||
   (oSession.responseCode == 307) ||
   (oSession.responseCode == 308))  { ... do redirect stuff }

It would be better if there were a way to test a bunch of codes at once in an Enumerable (e.g. oSession.ResponseCodeIn([301,302,303,307,308])

It would also be nice if you could do:

if (oSession.oResponse.IsStatusRedirect() || oSessionl.oResponse.IsStatusClientError() || oSession.oResponse.IsStatusServerError() || oSession.oResponse.IsStatusSuccess())

...where each method returns true for 3xx, 4xx, 5xx, and 2xx.

Fiddler should show a HTTP Protocol warning if a HTTP/301,302,303,307,308 response does not contain exactly one Location header.

i am recording chrome sessions in fiddler and when i login to my site with https it records all, but playing the webtest on visual studio it shows 302 redirect error on login page and then for all rest of the pages it shows that it is again trying to login. what could be the cause?

Repro:

1. Add a bunch of rules to the autoresponder.

2. Select two rules.

3. Right click the rules list.

Observe:

Only an "Export all" command.

Expect:

An "Export selected" command that exports only the currently-selected rules.

REPRO:

1. Connect to a network where there's no internet connection (e.g. unplug ethernet from the router)

2. Launch Fiddler.

OBSERVE:

Fiddler is not responsive to clicks for several seconds.

EXPECT:

Fiddler update check is fully asynchronous.

Click on a request or response that has

Content-Type: application/reports+json

EXPECT: JSON tab activates (e.g. scores this as if it were content-type: application/json

The XML Inspectors should do the same for content-types ending in +xml

Text is misleading if "Perform decryption" is selected.

Text is only correct in case "Skip decryption"

Currently, Microsoft Edge generates HAR files with a malformed HTTP version string, e.g.

"httpVersion": "HTTPS"

When Fiddler's HAR Import feature attempts to parse this data, it fails and this results in omitting *all* of the headers from display.

To mitigate this, Fiddler should look at the httpVersion string and if it lacks a slash, it should either add the slash (if this is enough to placate the response parser) or it should generate a dummy value for the entire token (e.g. "http/0.0") so that the rest of the header values are parsed correctly.

(I have filed a bug against Edge too).

It will be much easier to use and know of the package's existence if it is listed as a nuget package.

Please consider uploading the fidlercore packets to the nuget.

Could you please sign the certificate you use to distribute and deploy Fiddler.

I am generally very causes about what I install and like to see best practice efforts to ensure what I install is safe. to support user wanting to be safe and promote expectations of good behaviour from legitimate and honourable software supplies could you please sign the certificate (and ensure it is from a reputable CA).
