Is the incompatibility of youtube, facebook, amazon and even the microsoft website with several browsers with Win10 ever going to get fixed? I'm getting really annoyed. Never had these issues until this year.
I recommend basic troubleshooting. Do a completely clean reinstall of your favorite browsers, with no extra plugins or add-ons. Check your DNS settings. Scan your system thoroughly for malware. Upgrade your drivers (particularly network, graphics, and sound) in case there's a bad driver in the mix.
