1634302 - Devtools network request list selects multiple requests when clicking on one

Status: RESOLVED DUPLICATE of bug 1628162

(DevTools :: Netmonitor, defect)

Description

[Platon Pronko]

Attachment: network-tab.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

1. Opened developer tools, selected "Network" tab.
2. Navigated to https://hn.algolia.com/ (actually most other sites exhibit the same problem, this is just one example).
3. Started clicking on different recorder requests (to see headers and other information).

Actual results:

When I click on one request often several (two, three or even four) get highlighted. (see screenshot network-tab.png)

In headers list I see that headers are often not related to the request I clicked upon - in the example screenshot I clicked on request for js file, but in the request headers you can see "Accept: text/css". And response headers are also from a different request - "location: ttps://hn.algolia.com/packs/css/application-504e169e.css".

I tried saving the requests as HAR file and loading back. Grouping is now not present, but many requests show 0 status code and transferred size of -1 bytes. (see screenshot network-tab-har.png). And the headers are still wrong - I see "location: ttps://hn.algolia.com/packs/css/application-504e169e.css" in response headers for JS file request.
I'll attach the HAR file.

Expected results:

I expected only one request to be selected, and the request URL and request headers to correspond to actual requests.

@Platon, I have a test Linux build (and Max and Win) with a patch that could fix the problem. Can you please test it on your machine and let me know if you see any improvements?

https://treeherder.mozilla.org/#/jobs?repo=try&revision=806715efa8d69853d084bcfd85cc95b8c7184bdb&selectedTaskRun=ckZJ9z-4TaysMo2ui2bJVg-0

You can download the build target.tar.bz2 from the Job Details tab available at the bottom of the page.

I can't reproduce the issue on my machine.

Thanks,
Honza

I downloaded and extracted target.tar.bz2, ran included firefox executable. The issue still persisted, I still see multiple requests selected. Can I provide any additional information to aid debugging?
