Hi!
The “Secure Connection Failed” error usually means Firefox can’t establish a secure connection. you should clear youtube site data by going to Settings → Privacy & Security → Cookies and Site Data → Manage Data… → youtube.com → Remove. another way is to temporarily disable HTTPS-Only Mode to test. Clear cached web content. Also make sure to check your antivirus/firewall because some settings can block secure connections.
If it still doesn’t work, let me know and we can investigate further.
