Today, CONFIG.sDefaultBrowserExe and sDefaultBrowserParams are internal, default to Internet Explorer and they don't seem to be controlled by preferences.

There should be a preference like fiddler.ui.toolbar.BrowserList.Default and fiddler.ui.toolbar.BrowserListDefaultParams that allows override.

Not much more to say. Fiddler on Windows is absolutely awesome, but nothing comes close on Max OS X.

Please, please, please offer a native Mac OS X version. I'd hiply pay 4100 or more for it. I'd even pay that for an annual subscription.

In order to debug a website served on localhost by IIS Express you need to use localhost.fiddler to get traffic to show up in Fiddler, but if you use HTTPS you'll first get a warning that the certificate name does not match and you have to manually confirm this connection.

This is generally a good idea, but in the case of localhost and localhost.fiddler I think this warning should not be shown, as having to use localhost.fiddler is simply a technical restriction that Fiddler should know about...

See https://fiddler.ideas.aha.io/ideas/FID-I-369. Installing the new build (either from the website or the upgrade prompt) will fix this issue for you.

This is most likely a bug in either Windows, or a configuration problem in your environment. Does it still happen if you right-click Fiddler and Run As Administrator? Is there any text on Fiddler's LOG tab? If you try to change the system proxy settings manually to 127.0.0.1 port 8888 (In Fiddler, click Tools > Wininet Options > Connections > LAN Settings) do the changes "stick" after you hit OK and then reopen LAN Settings)?

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.

Typically, this implies that your server is returning a cookie or some other token that is not being dynamically bound by the Web Test. As a consequence, all subsequent requests are treated as bearing invalid authentication info, and attempt to redirect the request to the login page.

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"

Reproduction:

* expand columns in sessions grid that much it produces horizontal scroll.
* deselect all sessions

Cursor jumps to bottom right corner of the right monitor.
