2032751 - tab.audible is undefined on Android

Status: NEW

(WebExtensions :: Android, defect, P5)

Description

[Rob Wu [:robwu]]

On mobile, the audible property of a tab is computed from nativeTab.playingAudio:

That code originated from Fennec (old source), but does not work at all on Fenix.

bug 1962876 refactors the mechanism that reveals the audibility of a tab. I think that the desktop and Android implementations can become similar at that point.

Note: there is a report stating that desktop's currently implemented behavior is incorrect, see bug 1667585.

This is also dead code (there is nothing that registers the listener): https://searchfox.org/firefox-main/rev/0ae2fcae6a70566ab9e13e401480387b34911bad/mobile/shared/components/extensions/ext-tabs.js#178-185

once support for audible is re-introduced, an alternative needs to be implemented to make sure that tabs.onUpdated fires when the audible property changes.
