Here's a suggestion, let me know what you think: - we add a new actor method to the WalkerActor (the normal DOM walker that is, not the accessible walker) - this method could be named something like hasAccessibleProperties, and would take a nodeActor as argument - we remove this method here, and also the one you added in accessibility-panel.js - instead, we use the new one from the inspector, when the menu is created. The added value is not having to add these 2 methods here that link the 2 panels together somehow.

So this will slow down the opening of the context menu. I'm just concerned that it may be perceived by users as the inspector being slow. I would advise calling this now, but not awaiting the response. Instead, have a promise resolution handler that later go back to the item and enable/disable it as needed. Note that with my previous comment, you would not be calling this method here, but instead this.walker.hasAccessibleProperties(this.selected.nodeFront), or something like this. @@ +1527,5 @@ > + label: INSPECTOR_L10N.getStr("inspectorShowAccessibilityProperties.label"), > + click: () => this.showAccessibilityProperties(acc), > + })); > + } else { > + menu.append(new MenuItem({ I'm not entirely sure we should have an else part here.

The issue is still reproducible on WIndows 7 x64 on the latest Nightly version 61.0a1. (Build ID: 20180419224145). Should I re-open the issue or submit a new bug?

Sorry for the inconvenience, it was actually a misunderstanding I realized after acknowledging https://bugzilla.mozilla.org/show_bug.cgi?id=1453237.
