I cannot find Norton Toolbar in Firefox on my Mac

This problem can occur if you upgrade to the latest version of Mozilla Firefox 43 before the latest compatible Norton Security browser extension is installed. To fix this problem, manually remove the Norton Security extension in Firefox.

Manually remove the Norton Security extension in Firefox

  1. Open Mozilla Firefox.

  2. Click Tools, and then Add-ons.

  3. Click Extensions in the Add-ons Manager window.

  4. Next to Norton Security, click Remove.

  5. When the extension is removed, restart Firefox.

  6. After Firefox restarts, a prompt is displayed to add the Norton Security browser extension. Click Add, and complete the installation

Thank you!

Thank you for using Norton Support.
