You're facing an issue where Firefox isn't automatically installed as the default browser on Windows 10.
Firefox isn't found in the default settings menu; only IE and Edge are listed. The default button just launches the same settings app. The fix mentioned in the forum isn't applicable to Firefox, and reinstalling doesn't resolve issues. No errors detected during DISM cleanup.
Open Firefox and try again. If the issue persists, let me know.
Remove and reinstall Firefox from the official website. Download the latest version directly from firefox.com.
Check if you're adding Firefox to your personal profile folder or sharing it across all users.
Create a fresh user profile and check if defaults can be adjusted there. I've noticed unusual behavior when profiles become slightly corrupted.
