1766116 - onCreatedNavigationTarget not triggered when tab is created from external application

Status: NEW

(WebExtensions :: General, defect, P3)

Description

[igorlogius]

User Agent: Mozilla/5.0 (Windows NT 10.0; rv:1001.0) Gecko/20100101 Firefox/97.0

Steps to reproduce:

1. created an addon, which should prevents duplicate tab creation (from links and external applicaiton openers) by hooking into the onCreatedNavigationTarget event (ref. https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/webNavigation/onCreatedNavigationTarget )
2. sideloaded the addon into browser (via about:debugging )
3. clicked the same link in another application (thunderbird) or use xdg-open http://example.net 2 times.

Since the url/navigation target should be available at the time of the tab creation i currently assume this to be a bug, since the only stated reason when this event will not be fired is when a tab is created without a navigation target.

Actual results:

The onCreatedNavigationTarget did not fire and the browser instance opened 2 tabs with the the same link targets.

Expected results:

The onCreatedNavigationTarget event should have fired both times and the second tab creation should have allow the addon to instantly closed the duplicate tab.

Attachment: Addon to log onCreatedNavigationTarget events

I reduced the addon only show the "essential" part. (aka. that the event is not triggered)
It now only calls "console.log" when the onCreatedNavigationTarget event/callback is triggered.

By installing it and looking at the output (about:debugging => "This Firefox" => Inspect)
it should shows, that there is no event when links are opend via external applications (for example xdg-open "https://example.net")

Hope this is good enough for reproduction, if not, just let me know and i'll try to improve it.
And thanks for taking a look at this.

Hello,

Thanks for quick response.

I think that I managed to reproduce the issue using Nightly Firefox and Windows 10x64 , but please confirm that I correctly performed the steps:

1. I installed the provided addon via about:debugging , then I entered in the console from "Inspect" button in about:debugging tab
2. From Thunderbird, I clicked 2 times on "https://example.net link"
3. I checked if any event was fired, but no new events were recorded in the console and the duplicate tabs were opened without any issues.

If this is the correct way to reproduce the problem, I will try the scenario on Mac platform too and I will change the "Unconfirmed " status to "New"
