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.
- 1Confirm normal websites open in the browser without the extension connected
- 2Open the extension and refresh its location or access list
- 3Return to an available Free location or sign in again if the account session expired
- 4Try another available location
- 5Restart the browser and reopen the extension
- 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.
