Nope, didn't have to do that. I upgraded to Win 10, fired up Firefox and it was still my default browser, didn't have to go through the rigmarole on the site you linked to. I even uninstalled Firefox and reinstalled, dead simple.
You have done nothing but railed against Windows 10 the minute it came out. Why do you have such a bee in your bonnet about it? Google are as pervasive if not more so, so why just pick on MS. Or is it an easy target?
Anyway I've said enough.
