1659040 - firefox dev edition not able to access internet intermittently

Status: RESOLVED INCOMPLETE

(Core :: Networking, defect)

Description

[ketu.bhalerao]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:80.0) Gecko/20100101 Firefox/80.0

Steps to reproduce:

download firefox dev edition.
install firefox dev edition
launch firefox dev ed, and browse internet.
after a while the spinners just spins, pages do not get loaded.
verified this with other browsers and other devices in my house and internet connection works fine.

Actual results:

the loader on tabs just shows loading. no page gets loaded.
this issue is now appearing very frequently for me.
I can be even in middle of the youtube video and the page goes in the loading state.
half the time when I start firefox I have to wait a good 5-10 mins before its usable (internet is not accessible)

Expected results:

when firefox is started I should be able to access the internet right away.
internet connectivity should not be lost if my internet connection is doing well.
there should not be an initial load time for the browser.

Hi Reporter,

Could you try to get the http log when you see this happens?

Thanks.

Thanks for the log.
It looks like someone suspend the http request but never resume it. This could be caused by some extension.
Could you try to disable all extensions and see if you can reproduce this?

If this issue still existed after disabling all extensions, could you add nsChannelClassifier:5 in MOZ_LOG env and capture the log again?

I disabled all the logs and tried to access however the issue is still there.

Unfortunately, we still can't tell what's wrong from the log.
May I ask you to also get the logs of child processes? To do this, you probably need to disable sandboxing first.
I assume that you are using windows. Here are the steps.

1. Open windows command line tool.
2. Go to firefox's folder. In my case it's: C:\Program Files\Firefox Nightly.
3. Type set MOZ_DISABLE_CONTENT_SANDBOX=1
4. Run firefox.exe.
5. Capture the log when the issue happens. When you click stop logging, you should be able to see logs created by child processes. The file name is like log.txt-child.xxxxx.moz_log. Please upload logs from main and child processes.

Thank you.

sure,
just to be clear, setting the flag and running the firefox.exe will be done from the same command prompt rt?
if i start firefox from my regular icon/app sandbox will be to its default state (i assume enabled)

Right, in the same command prompt.

I see a the channel bein cancelled from a YT script:

805303f4 is NS_ERROR_DOM_BAD_URI which we only return from here in HttpChannelChild, but could also come from somewhere else maybe.

Kershaw, do you have any ideas?

Comment 13

[Kershaw Chang [:kershaw]]

This is weird. I have no idea why channels are cancelled. Even cancelling by YT script is not reasonable to me.

So, I'd like to ask for more information.

1. Does this issue only happen on dev? Have you tried to use nightly or release?
2. Any steps to reproduce this issue?
3. I see SockJS running locally and the request is also cancelled. Maybe this is related?

4. When this happens again, could you try to access some simple website, such as www.example.com, and also capture the logs?

Thank you!

Sorry for the delayed response.
as suggested I have uninstalled all extensions, and here is the log file
I have used google.co.in, fast.com, golang.org website after things stopped working.
since yesterday firefox dev edition and the stable release have started giving a lot of issues. for me all day long it's stuck in not responding state. if I kill it using the task manager and try to start it again it won't start. every time I click firefox a process gets started but the browser does not come up. if after an hour or so it comes up it will straight away go into a not responding state and will not come out of it.
I need to restart my laptop in order to get firefox to work again. and even after a restart, it will only work for 5-10 minutes and then the same thing happens again.
this is really frustrating. I am using firefox dev edition for a couple of years and firefox for more than 6-8 years this is the first time I am so frustrated that I have started using Chrome as my main browser.
hope this gets resolved soon and I can go back to using firefox.

updated child file with nsChannelClassifier:5 and set MOZ_DISABLE_CONTENT_SANDBOX=1

the child file had no content, bugzilla not allowing to attach empty file

Comment 16

[Kershaw Chang [:kershaw]]

Thanks for the log.

Unfortunately, I can't find the root cause from the log. I can only tell it seems there is something wrong with your network environment. For example, the http request to google.co.in is failed because of timeout.
The http request is created at 2020-10-20 07:32:16.

After about 30s, the request is failed because of timeout.

Dragana, since you are on triage this week, could you also take a look at the log? Just in case I missed something.
Thanks.

the issue is with firefox (stable and developer editions). even on the same laptop other apps/browsers works as expected. other devices in the same network do not show these issues.

I uninstalled the firefox developer edition thinking maybe the installer was corrupted this is a new issue I am facing.

Comment 19

[ketu.bhalerao]

Hi,

i got a resolution for the installation issue I was facing (https://bugzilla.mozilla.org/show_bug.cgi?id=1672442)
i installed a freshly downloaded firefox version: Firefox Setup 83.0b5
as per the prompt, I ignored all the import previous settings to keep the firefox installation clean.
also refreshed the firefox as well after installation (there was a prompt for that as well)

now it's a clean freshly installed firefox dev edition with no extension, no account (since i can't connect to the internet), no settings changes.
the issue of not able to connect to the internet is still there.

Hello, could you test again with the latest firefox and see if you can still reproduce this?
Thanks.
