@ocdtrekkie: “Pretty sure the user is wrong about what caused this dialog. It was the recent Firefox update.”
Explain like I'm five how a firefox update would set the default browser to EDGE ;]

It didn't. The person who posted this didn't read the screen, and fundamentally misunderstood it. The title of the post is wrong.
You'll notice that the dialog is asking "How do you want to open .pdf files from now on?" Because Firefox can now be set as a default PDF reader, Windows has a new PDF reader option, so it asks the next time the user tries to open a PDF. (And this has nothing to do with being the default web browser or not.)
Next, the user also incorrectly assumed this had set the default to Edge. This is again, because they didn't read. Microsoft has broken out the "Featured in Windows 10" option from the "Other options". But it's asking, it hasn't made a change yet.
Note that if you install any web browser, Windows will do this.
I guess the main difference between this Edge install and any other browser is that only Edge gets an automatic placement in the bottom taskbar, next to the start button. No other browser I installed have ended up there automatically.
But many complaints about Windows are trumped up a bit by misunderstanding what actually happened.
