extension added Firefox doorhanger from hamburger menu loses focus when dismissed


(Core :: Disability Access APIs, defect, P2)

(Whiteboard: [smoketest] [mac2020_2])

When installing an extension, you get a doorhanger dialog from the hamburger menu. Focusing it with F6 and activating "Okay, Got it" button sends focus to nowhere.

Steps to reproduce.

  1. Visit the add-ons manager from the Hamburger menu.
  2. Install Tree Style Tabs extension from the recommendations section.
  3. F6 to focus the doorhanger dialog that appears from the Hamburger menu.
  4. Activate the "Okay, Got It." button.

Results: focus goes to nowhere.
Expected. Focus returns to previously focused item after dialog goes away.

Tested on today's Nightly build on Mac OS 10.15.7

Summary: extension added to Firefox doorhanger from hamburger menu loses focus → extension added Firefox doorhanger from hamburger menu loses focus when dismissed

We'd need to test this on Windows to be sure, but I'd say this is a front-end bug. There are a few cases with Firefox UI pop-ups where focus goes to limbo after they're dismissed. That said, if this breaks VO in a big way, it'd be nice if we could somehow detect situations like this and be a bit more resilliant.

Severity: -- → S3
Priority: -- → P2

Currently getting the same behaviour when navigating a submenu inside a submenu on a context menu. Not sure if this is the same thing, or some NSWindow weirdness, but documenting here for now


  1. Install LeechBlock addon
  2. VO+Shift+M in content
  3. Navigate VO+down to leechblock submenu
  4. Enter submenu and navigate to "Add Site" submenu

entering the second submenu should allow navigation of the submenu's contents

trying to enter the submenu loses VO focus
