Status: RESOLVED INCOMPLETE

(WebExtensions :: Request Handling, defect)

Description

Attachment: webrequest-oncomplete-bug-report.zip

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20180920131237

Steps to reproduce:

1. Load the attached extension
2. Open the background page for the extension and view the console
3. Navigate to linkedin.com
4. Login to linkedin.com
5. The console should show the request data, but does not show the matching response
6. Repeat steps 1-5 in Chrome.
7. The console should show both request data and matching response


Actual results:

In Firefox, the login response for Linkedin is never captured by the WebRequest API via onComplete nor onResponseStarted. However, in Chrome the matching response is captured just fine.


Expected results:

The login response should be captured by WebRequest's onComplete method like it is for most other website's login requests. Chrome does not have this issue.

This worked fine for me in recent Firefox 64.
Does this occur for you in a fresh profile with Firefox Nightly?

Andrew -
I tried the above steps on Firefox 64 (Nightly) and still seeing the issue. I've attached a screenshot comparing the logs from the extension in Firefox Nightly (on the left) and Chrome (on the right). Notice the log 'matched the request successfully' on the Chrome console but not Firefox's console.

Can you reproduce this in a fresh profile?  If you have another extension installed that blocks some requests or even something like tracking protection enabled, that could affect http requests.
