1887952 - OPEN_URL trigger listener triggers on background tabs

Status: NEW

(Firefox :: Messaging System, defect, P2)

Description

[Jason Prickett]

When using the OPEN_URL trigger listener, if one of the target URLs is loaded in a background tab, the trigger listener will fire, potentially displaying a message before the user has actually navigated to the URL in question.

I believe trigger in original description of the bug is openURL

I believe we can do something nice with a TabSelect listener. If the tabs progress listener fires on a background tab, save that tab in a WeakSet. Then when a TabSelect event fires, we can check if the target is in our WeakSet, and if so, call the triggerHandler. There's an example of a TabSelect handler in the pdfJsFeatureCalloutCheck trigger listener.
