1863977 - MSIX Nightly build shown in Windows settings as the default browser but in reality its not the default one

Status: RESOLVED DUPLICATE of bug 1863980

(Firefox :: Installer, defect)

Description

[Bogdan Maris, Desktop Test Engineering]

Found in

• MSIX Firefox 121 Nightly

Affected versions

• MSIX 121 Nightly

Tested platforms

• Affected platforms: Windows 10 22h2.
• Unaffected platforms: MacOS, Ubuntu

Steps to reproduce

1. Install MSIX Nightly build
2. Make MSIX Nightly default browser
3. Very that the default browser is Nightly
4. Change the default browser to any other browser (except Nightly)
5. Close Nighty build and reopen it (so that the Set as default notification appears)
6. Click the Set as default browser from the notification

• Windows settings window opens and MozillaFirefoxNightly is shown as default

7. Go to Settings in Nightly and check if its set as default

Expected result

• Nightly is set as default browser

Actual result

• Chrome or any other browser used in step 4 is still the acting default even though in Windows settings MozillaFirefoxNightly is shown as the default one. Having a html file on disk and duble clicking it will open in Chrome or any other browser used before not in Nightly.

Regression range

• Not a regression range since this is a new implementation

Additional information

:bmaris, if you think that's a regression, could you try to find a regression range using for example mozregression?
