Comment 22

[Manuel Bucher [:manuel]]

It is only reproducible without --headless option to me. Running the test with ./mach test browser/base/content/test/contextMenu/browser_strip_on_share_link.js. The error occurs almost every time for me. With --headless no errors occur.

This one is a bit weird. It seems like the "popupshown" event is handled before "popupshowing". Calling contextMenu.activateItem might require more preconditions than just that the "popupshown" event was emitted.

1. gContextMenu is initialized in "popupshowing"
2. gContextMenu is still null when clicking on the context menu link "Strip without Site Tracking"
3. In the test we wait until the context menu emitted the signal "popupshown"
4. we even assert that it is visible
5. adding an await new Promise(r => setTimeout(r, 50)); here makes the intermittent test failure go away. Suggesting this is really a race condition between the two event handlers.

Potential fixes is to do a simple waitForCondition for gContextMenu != null or to emit another signal after initializing gContextMenu and waiting for that signal.
