Pin notification does not appear anymore in a Windows session if stressed enough (no clear steps for now)


(Firefox :: Installer, defect)

Firefox 127

Found in

  • Latest Nightly 127.0a1

Affected versions

  • Latest Nightly 127.0a1

Tested platforms

  • Affected platforms: Windows 11 Dev and Canary channels only - 24h2 (26080.1 and 26100.1)
  • Unaffected platforms: MacOS and Ubuntu

Steps to reproduce

  1. Install latest Nightly (.exe)
  2. Visit about:welcome page
  3. Leave only Pin Nightly to taskbar checked
  4. Click on the Save and continue button
  5. Repeat the above steps a few more times

Expected result

  • A system notification is displayed asking the user to pin Firefox to taskbar.

Actual result

  • We reach a point where the notification does not appear anymore even after a browser restart, the only "cure" we found is to restart the Windows machine.

Regression range

  • Not a regression since this is a new implementation.

Additional notes

  • Unfortunately we don't have exact steps for this at this time, we'll try and find some asap.
  • I said to have this logged for now and edit it as soon as we have clear steps for this scenario.
