1561386 - Network Information API: missing downlink attribute causing infinite loading on ads.google.com

Status: RESOLVED WONTFIX

(Core :: DOM: Device Interfaces, defect)

Description

[Ksenia Berezina [:ksenia]]

As described here:

https://github.com/webcompat/web-bugs/issues/32982

Steps to reproduce:
On Firefox on Android sign in to your google account and go to the following link:
https://ads.google.com/aw/overview?ocid=338200999&__c=5875343151&authuser=0&__u=9047806137&mode=real&type=mobile&enableAllBrowsers=1&mobile=1

Expected:
Site loads

Actual:
Site doesn't load

Looks like even though window.navigator.connection property exists in Firefox for Android, window.navigator.connection.downlink is missing, which is causing the error, so the site never loads.

Neha, do you know if this is on any roadmap?

I don't know but Daosheng will probably know.
Daosheng, also, can I file the request to make you the triage owner for Device Interfaces?

I think this is because Gecko hasn't implemented downlink attribute in window.navigator.connection yet [1]. We can consider to follow up the recent changes in Network Information API from W3C draft [2].

:neha, I don't know anything about the roadmap of Device Interfaces, it is not covered by my radar.

Google fixed the affected sites, so this is less pressing. Also, https://github.com/mozilla/standards-positions/issues/117

The severity field for this bug is relatively low, S3. However, the bug has 5 See Also bugs.
:cmartin, could you consider increasing the bug severity?

Closing this bug as WONTFIX.

Google fixed the upstream problem, which is that their website didn't function properly without this API.

The second part of this is that we likely won't be implementing the Network Information API as-is, since Mozilla considers the standard itself to be "harmful".
