if you reboot your computer on Windows 10 with fiddler open, then it kills your network connection. One the computer boots up again, you have to reopen fiddler.

In the Good Old Times™ "give feednback" just mean "give feedback".

Well, here is your feedback.

Why do i have to

  • create an account I need like Aids
  • confirm the account  I need like Aids
  • set a password to an account I need like Aids
  • log in with said account I need like Aids
  • click the "report bug" button (finally)
  • getting interrupted again by some page who tries to trick me in a fucking search
  • find the "yes I really really want to report that bug" button
  • and finally after all the above being able to GIVE SOME FUCKING FEEDBACK?

Why are you wasting my time? I did not make it buggy, it was you!

1. 在代码里Fiddler有什么方法可以把发送的请求信息记录到Composer History列表?(重点

2. 点击Excute按钮,是怎么把请求记录下来的?记录的请求保存在什么位置?

We downloaded Fiddler Classic from our site for evaluation, and when we try to distribute it via Google Drive (we are enterprise subscribers), we get a virus warning, and the download is not allowed.

I'm guessing this is a false positive, but want to verify that with you, and see if you know why it might be flagged as virus by Google's scanning service.

We are holding off distributing or evaluating the product for now, erring on the side of caution.

Please consider refraining from (or at least making optional) the sorting of the JSON property keys when using the JSON tree viewer.  For code which sends out complex payloads, having the properties reordered makes it hard to compare the tree to the actual payload sent.  For example, we send startXXX and endXXX properties at the end of our payload, and when Fiddler moves "endXXX" to the top of the tree, debugging becomes a pain.  Please allow the payload to be tree-visualized as constructed.
