Default settings not working on Current Windows 11

I’ve been running (always up to date) FF on windows as default for years. With the recent update of MS edge (which I also run, but not as default), the standard default settings (Default App settings) no longer work, locking HTTP and HTTPS protocols strictly to MS edge with no ability to change them.

Yes, I’m using the standard way (which always worked before) but now it’s irredeemably busted for me.
