How to set browser for debugging web app

I recently changed my default browser from Google Chrome to Firefox with Chrome removed from the computer. Now the debugger launches my web apps in IE 11. How can I change that to Firefox?

You have to make Firefox your default browser. We just use ShowURL.

in windows 10 at settings, search “browser”
then there should appear choose your browser.
its at standard-apps.

Firefox is the default browser. It must be some kind of Windows issue because it works fine on my laptop.
