1700738 - dev tools duplicate request

Status: RESOLVED INACTIVE

(DevTools :: Netmonitor, defect)

Description

Attachment: Screen Shot 2021-03-24 at 15.12.49.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:86.0) Gecko/20100101 Firefox/86.0

Steps to reproduce:

1. Open dev tools network tab.
2. (optional) disable cache
3. Visit https://admin.debtcompliance.co

Actual results:

In dev tools, the network tab shows the same request twice (application-f6430116aa559fa06f05.js).

Expected results:

The network tab should only show this request once.

The request comes from a <script> tag in the HTML. There is only one such <script> tag. So, there should only be one such request.

Chrome dev tools' network tab correctly only shows this request once.

I've been using FF dev tools since they were called Firebug. <3 FF. Keep up the good work!

Server log for FF activity shows two identical requests

... method=GET path="/packs/js/application-f6430116aa559fa06f05.js" ... status=304 bytes=112 protocol=https
... method=GET path="/packs/js/application-f6430116aa559fa06f05.js" ... status=304 bytes=112 protocol=https

Server log for Chrome activity shows one .js request and one .js.map request

... method=GET path="/packs/js/application-f6430116aa559fa06f05.js" ... status=304 bytes=112 protocol=https
... method=GET path="/packs/js/application-f6430116aa559fa06f05.js.map" ... status=200 bytes=1179662 protocol=https

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

Thanks for the report!

I am not seeing the application-f6430116aa559fa06f05.js request at all in my case. Did anything change with the page?

Also, I am seeing that you are using Firefox 86
Can you also try Firefox Nightly?
https://www.mozilla.org/en-US/firefox/channel/desktop/

Do you see the issue in Nightly too?

I can reproduce.

I am not seeing the application-f6430116aa559fa06f05.js request at all in my case.

The hash probably changes regularly as they make changes on the website. Just look for application-{somehash}.js.
The way I consistently get it twice is:

• open about:blank
• open devtools > netmonitor
• disable cache
• navigate to https://admin.debtcompliance.co

I see a bunch of duplicated requests, but they're all missing information, so hard to tell where they're coming from.

Here's what I see for my STRs, but it seems different from what the reporter logged. Might be more related to target switching than to actual duplicated requests.

Jared: restoring the needinfo for you. We can't really reproduce your issue so far. Did you have a chance to test with a more recent version of Firefox?

Jared, please see the previous comment. Could you please test this for us, thank you!

No answer for more than a month (considering the initial ni? was 2 months ago).
Not actionable, closing for now, but feel free to reopen if relevant.
