Status: RESOLVED DUPLICATE of bug 1467522

(DevTools :: Netmonitor, defect)

Description

[Dan Wolff]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

1. Open a new tab
2. Open the Web developer tools, go to the Network tab
3. Enter a JSON file in the location bar (e.g. https://danwolff.se/2018/contenttype.php?ct=application/json)
4. The request appears in the Network tab. Right-click the row, and select "Edit and resend"
5. A "New request" panel appears to the right.
6. Click "Send"


Actual results:

The button is focused, but nothing else.


Expected results:

The request should have been sent.

-------------------

More information:

- JSON requests work when part of a webpage.
- Other content types seem to work (HTML, XML, CSS, JavaScript, plain text).

I get the following errors in the Browser Console:
