1625666 - Can't select single request in Network Monitor

Status: RESOLVED DUPLICATE of bug 1628162

(DevTools :: Netmonitor, defect)

Description

[[e-mail]]

Attachment: netbug.png

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

On a fresh install (I deleted my profile under ~/.mozilla) of Firefox 74.0 (64 bit) (the latest one that ships with Fedora 31) I can't use the Network Monitor properly.
Perhaps the behaviour has changed on this release but I cannot select a single request in the Network Monitor tab. Some requests are bundled together with others for no obvious reason (in a consistent way tho).

Actual results:

Expected results:

Before this bug I could select all requests on their own, just one at a time, to inspect them. This bundling doesn't allow me to inspect some requests, whenever they get bundled together with others. I assume this is a UI bug.

@David, I have a test Linux build 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?

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
