1645252 - Network tab is grouping requests

Status: RESOLVED FIXED

(DevTools :: Netmonitor, defect)

Description

[rael.gc]

Attachment: network_tab.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

Open any page, open Network tab (Ctrl +E), reload the page.

Actual results:

Some network requests are grouped, so they cannot be inspected individually. See in the attached screenshot how I clicked in one request and 3 got selected (and I can inspect only the first).

Expected results:

Every request should be selectable individually, so we can inspect headers, responses, etc.

I tested this with all plugins disabled, including other profiles too: same results.

Thanks for the report!

This is known bug and it would be great if you could provide a simple test case (an online page or attach a test page) we could use.
That would be great help.

For me, even opening this current URL this bug happens:

1. Open Network tab (Ctrl+E)
2. Visit https://bugzilla.mozilla.org/show_bug.cgi?id=1645252
3. Watch requests and see how a lot of them are grouped.

@bomsy, can you reproduce this?
I don't see it on Win10

In any case it looks like the same problem as described here

I can't seem to reproduce it.
i tried Fx 77 / MacOS and Fx 76 / Ubuntu linux running on Virtualbox.

Can you try latest Firefox on Ubuntu? I facing this issue on 77.0.1, it was not present on 76.

Comment 8

[Hubert Boma Manilla (:bomsy)]

hmmm ... Yes just tried 78.0 nightly still can't reproduce.

Comment 9

[Hubert Boma Manilla (:bomsy)]

Also had @Nicloas check fx 77 on ubuntu and he can't repro as well.

@rael

I just tried with 79.0a1 (2020-06-14) (64-bit) and unfortunately, still the same issue.

Guys, really thanks for all the attention, I can see that you're really trying to reproduce this issue and that it appears to be an edge case.

Sorry for not being able to give you more details, but in my work machine happens for every user, even on safe mode (no extensions loaded).

Later I'll try in a different machine with Ubuntu 18.04.

Comment 11

Just tested in my other machine with Ubuntu 18.04 and Firefox 77: not reproducible.

Good, at least it appears to be an isolate issue.

The other weird behavior I've noticed in my affected machine: for the "grouped" requests, status, type, size and other infos are all missing.

I tested this with other users, disabled addons, even with nightly and ESR firefox versions: this issue is still present on this machine. Should I try "reset" my Firefox install? I mean, something like sudo apt purge firefox, then remove all configurations and reinstall?

Comment 12

[rael.gc]

Guys, I even purge all Firefox install and configurations (global and user) and issue continued. Until I reboot the machine and boom, all back to normal.

Hi rael.gc,

I just tried with 79.0a1 (2020-06-14) (64-bit) and unfortunately, still the same issue.

Could you test the lastest nightly 79.0a1 (2020-06-25) (64-bit) on this your version on ubuntu again?
Likely fixed by Bug 1644275

thanks

After a reboot, the issue was gone and I cannot reproduce anymore.

Before the reboot, no matter the version I try to install (I've installed nightly, ESR, tried other users on same machine), it was always happening.

Wondering if DevTools relies on any system library, and that library had any kind of issue (my system, on the time of issue, had a restart request pending).

Thanks so much rael for your help on testing.
I'm closing this for now.
Feel free to reopen if you see the issue again.
