how can i add trusted websites to the safe list

You can add websites to your exceptions: https://support.mozilla.org/en-US/kb/manage-enhanced-tracking-protection-exceptions

The exact steps depend on which browser, antivirus, or security software you're using. In most cases, look for a **Whitelist**, **Safe Sites**, or **Exceptions** section in the settings and add the Zynga website there.

If you let us know which program is blocking Zynga Games, someone can provide more specific instructions.
