Status: NEW

(GeckoView :: General, defect, P2)

Description

[William Durand [:willdurand]]

I am seeing this error all the time (for quite some time now), in both logcat output when using Fenix or in the output of some gecko (toolkit) tests running on Android:

[JavaScript Error: "TypeError: can't access property "eventDispatcher", this.window.moduleManager is undefined" {file: "resource://gre/modules/GeckoViewActorParent.sys.mjs" line: 28}]
get eventDispatcher@resource://gre/modules/GeckoViewActorParent.sys.mjs:28:5

I'm noticed this as well. Going to bump this in our next triage meeting.

+1, this always catches my eye as a false-flag when debugging too.

I have investigated this before. I think that it was due to top-level loads that aren't geckoview.xhtml, such as the dummy page that's loaded in a ContentPage in xpcshell.
