Status: RESOLVED DUPLICATE of bug 1752270

(Core :: Networking, enhancement)

Description

[shahtufail117]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

Loading facebook and upwork and other web based services and stops loading content after a few 10 or 15 of them.

Actual results:

Facebook content stops loading and says to refresh, and sometimes upwork also stops loading content after a while.

Expected results:

the content should be loading one after the other in an infinite scroll

It starts to work again only after i clear cache and refresh, all in all i have to do this after every two or so hours.

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Panning and Zooming' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Comment 3

[Botond Ballo [:botond]]

Not sure what the best component for this is, but Networking might be a good start.

Comment 4

[Dragana Damjanovic [:dragana]]

Eden, can this be related to service workers? I do not really see that this can be necko issue.

Comment 5

[Eden Chuang[:edenchuang]]

Not sure if it is related to a service worker issue or not.
Need more information for debugging. Unfortunately, I could not reproduce it in my local.
According to comment 1, it is probably a regression of bug 1722502. However, it needs to be confirmed.

Just a guess from a high-level view that if quota mitigation fails, it is possible to meet the case.
I will take a look to see if there is a case that makes the quota mitigation fails.

Since this seems difficult to reproduce, could you assist us with using mozregression to figure out when the bug started happening: https://mozilla.github.io/mozregression/quickstart.html
This should confirm if comment 5 is correct.

Comment 7

[Eden Chuang[:edenchuang]]

I meet the loading stop once with nightly 94, but it is not the issue I mentioned in comment 5.

Important Update.
I found a way to reliably replicate the bug.
It's also happening at certain other sites. For example, you can cause the malfunction by doing the following:

1. Go to https://www.lifeextension.com
2. In the search box at the top, type something and hit the Enter key.
   Result: Firefox malfunction - search results page never loads.

I have tested this on 3 different PCs and also in troubleshooting mode.
The page works fine in Chrome!

Not sure why I can't reproduce this locally.
Could you try to capture a http log?
Thanks.

The issue happens sporadically. I've captured a log for https://www.lifeextension.com when using the product search on the page.

Thanks for the log.
It shows that the connection to www.lifeextension.com is closed by the server, since we read 0 byte from the socket.
However, it's unclear why the server closes the connection.

It's probably worth to mention that the issue related to www.lifeextension.com may not the same as facebook, since we connect to www.lifeextension.com via http/2 and facebook is via http/3.
