I am running the RTM Windows 10 Home build 14293.321 and I too got the 'Vintage Web Tech..' page with Edge. However, if you type about:flags into the address box you get access to the Developers Settings. Turn off 'Use Microsoft Compatability List' and it works, turn it on again and it stops working - go figure...
My Firefox didn't work at first either. I tried clearing the cache and any Microsoft-related cookies but nothing worked. Now, after a restart of Windows my Firefox works too. Not sure what fixed it, but I'm not complaining :)
