Windows 10: Latest Win10 update has blocked Firefox as default browser, locked Edg

The morning of May 25th 2019 Pacific Time Microsoft locked in MS Edge as a default browser in Windows 10 on my computer.

My system shows 2019-05 Cumulative Update for Windows 10 version 1809 for x64-based Systems (KB4494441) successfully installed on 5/23/2019 (yet yesterday, 5/24 Firefox was still my default browser)

Please read the following methods to see how they did it. Bottom line: Firefox, Chrome or any other browser are not recognized by Windows 10.

Settings>default apps>web browser
Microsoft Edge or "Look for app in Microsoft Store" (of course neither Firefox nor Chrome nor IE11 are listed there)

Settings>default apps>"choose default apps by protocol"
HTTP and HTTPS are locked in by MS Edge, no way to change

Settings>default apps>"set defaults by app"
Firefox nor Google Chrome nor IE11 are listed

Does anyone have a fix. What can we do?

win10 1709 default apps: browser list not updated (no firefox, uninstalled browsers still there)

win10 enterprise 1709 16299.125

in "default apps", the web browser lists isn't updated with installed browsers anymore

• "vivaldi" is still listed even though it isn't installed (selecting it causes an error each time an URL is invoked, as vivaldi isnt' there anymore)
• "firefoxc" isn't listed and can't be selected as default browser even if it's installed
• the list regularly shows "chrome", "ie" and "edge"

I can only select Firefox as default browser choosing defaults by protocol http/https

obviously something got corrupted and the list got out of sync

any idea where in the registry or elsewhere that list is stored, so that I can manually fix it?

I managed to manually remove "vivaldi" by deleting all registry keys referring to vivaldi, but I couldn't restore firefox even manually adding the "firefoxHTML" values next to the "chromeHTML" values

I'm looking for a solution to manually restore the correct installed browser list, regardless of the default browser

Firefox not showing as default browser?

HI Zane, sorry you’re having these troubles.

Here are the steps I would take:

Let’s run through some items to try to fix Edge.

Reset Edge. Click start - settings - apps - find Edge on the list. Click on it, and then advanced, terminate, then hit reset. Make sure it’s strong hold on anything is gone.

Now, uninstall Firefox, reboot, reinstall.

See if you can now assign Firefox as your default browser.

Good luck, and let me know!
