Change Firewall settings

Computer firewalls sometimes block YouTube videos from playing.

Here’s how to find your firewall settings:

  • For PC users: click the Start menu, click Control Panel, click Security, then click Windows Firewall
  • For Mac users: click System Preferences, click Security & Privacy, click the Firewall tab
Temporarily disable ad or pop-up blocking software

It’s possible that YouTube is being blocked if you have ad or pop-up blocking software installed on your computer. Here’s how to check your computer for ad or pop-up blocking software (like Norton anti-virus):

  • For PC users: click your computer's Start menu, then click All Programs
  • For Mac users: click Finder, then click Applications
