Browser extension is not connecting

3 min read·Updated September 16, 2026

Refresh the official Chrome or Firefox extension without exposing browser proxy or credential internals.

  1. 1Confirm normal websites open in the browser without the extension connected
  2. 2Open the extension and refresh its location or access list
  3. 3Return to an available Free location or sign in again if the account session expired
  4. 4Try another available location
  5. 5Restart the browser and reopen the extension
  6. 6Update or reinstall only from the official Chrome Web Store or Firefox Add-ons listing
  • Temporarily disable another proxy or VPN extension that may control the same browser setting
  • Check whether a work or school browser policy prevents proxy extensions
  • Use the full HorizonVPN app if traffic outside the browser also needs protection

Do not paste proxy hostnames, ports, passwords, PAC scripts, or browser-policy values from another guide. The extension receives and applies its released connection data automatically.
