want to know the encryption level when using a VPN for the Windows Firefox extension.

Hello @user13634
Are you referring to Norton VPN - Fast & Secure – Firefox browser extension ?

Norton VPN browser extension lets you control your VPN status and connected location, plus turn Ad Blocker on/off.
https://addons.mozilla.org/en-US/firefox/addon/norton-vpn-fast-secure/

Norton designed its browser extension to act as a remote control and direct interface for the system-wide Norton 360 desktop app.

What Actually Happens When You Click the Extension

• Direct Desktop Control: When you toggle the VPN on or off inside Firefox, it sends an immediate command to the main Norton 360 background engine installed on your PC.
• System-Wide Action: Turning it on in Firefox actually fires up the full system-wide desktop VPN, protecting your entire machine (not just the browser).
• Unified State: If you open the Norton 360 desktop app dashboard, you will see the status matches exactly what you toggled inside Firefox.

Install Norton VPN extension on your browser
Enable Ad Blocker in Norton VPN browser extension

Norton VPN browser extension works the same way with the standalone Norton VPN desktop app.
Norton builds just one unified Norton VPN Firefox extension. It is programmed to detect and establish a direct connection link with either the main Norton 360 suite or the individual standalone Norton Secure VPN desktop client.

Since, we’re talking about Norton VPN extension:

============

Norton Neo supports Chrome extensions via the Chrome Web Store.

Technically, you can install Norton VPN extension inside Norton Neo because Norton Neo is built on Chromium and fully supports Chrome Web Store extensions. However, you should not use Norton VPN extension inside Norton Neo, as doing so is completely redundant and will likely cause software conflicts.

Here is what happens if you try to use the Norton VPN extension inside Norton Neo:

1. It Defaults to a “Double-Tunnel” Conflict
   Because Norton Neo already has its own built-in, autonomous VPN engine, keeping it active while simultaneously turning on the Norton VPN extension creates a conflict. The browser will try to force your data through two separate Norton routing processes at once, which usually results in frozen web pages, slow load times, or a broken internet connection.

2. The Extension Overrides Your System, Not Just the Browser
   As mentioned before, the Norton VPN extension is just a remote control switch for your desktop Norton 360 app. Turning it “On” inside Neo will forcefully activate the device-wide VPN. This defeats the main purpose of using Neo’s localized browser tunnel, which is designed to keep your background system traffic separate and fast.

Correct Norton Neo Setup:
To get the cleanest experience without errors, you should:

• Uninstall or disable the standalone Norton VPN extension inside Neo.
• Rely entirely on Neo’s native, built-in VPN toggles for your web tabs.
• Open the separate Norton 360 desktop app directly if you ever need to turn on full-device protection for apps outside of your browser.

The standalone Norton VPN browser extension and the Norton Neo built-in VPN serve completely different roles:

The Norton VPN Extension (The Switch)

• What it does: It acts as a remote control desktop shortcut for your standalone Norton 360 app.
• The impact: Flipping it to “On” triggers the desktop app to encrypt your entire computer (all apps, background tasks, and games).
• Requirement: It requires you to have the heavy, paid Norton 360 desktop suite actively installed and running on your PC.

The Norton Neo Built-in VPN (The Autonomous Tunnel)

• What it does: It is a self-contained, native browser feature engineered directly into the Norton Neo browser.
• The impact: It operates completely independently of any desktop software, encrypting only your web tabs while ignoring the rest of your machine.
• Special feature: It uses a specialized “VPN for Agents” protocol to automatically flip itself on when you visit risky, banking, or medical sites, then clicks off when you leave.

Because you are using Neo, you do not need that separate switch extension at all. The browser takes care of its own localized tunnel natively

The Norton Neo VPN uses a specialized, proprietary protocol engine called Norton VPN for Agents. This protocol was built specifically for the AI browser to create an isolated, encrypted tunnel not just for your tabs, but specifically for the background AI requests. This ensures that your local AI interactions cannot leak your true IP address to cloud servers.

No Protocol Selection Menu
In the Norton 360 app, you can open the settings menu and manually switch between protocols like:

• WireGuard (for top speeds)
• Mimic (Norton’s custom protocol for bypassing strict firewalls)
• OpenVPN / IPSec

The Norton Neo browser does not give you these options. It handles all protocol handshakes automatically in the background to ensure the “Adaptive VPN” feature can turn itself on and off seamlessly without breaking your browsing session.

If you need a specific protocol for gaming or downloading files, you will need to continue using the main Norton 360 application interface rather than the browser.

Gen Digital’s official media announcement, Norton Neo Raises the Bar on Security and Privacy for the AI-Native Browser, details the specific mechanics:

• Adaptive Protection: The documentation explicitly highlights its ability to “intelligently apply protection when needed” (like banking/health sites) and automatically step back during everyday browsing.

• No-Log Guarantees: It officially details the strict contractual safeguards ensuring that localized data stays yours, and cloud-assisted AI tasks are stripped of identifying user metrics.

• The “VPN for Agents” Protocol: Documentation shared during the roll-out notes that it relies on a multi-tunnel network layout. This isolated architecture ensures that when your browser communicates with AI large language models in the cloud, that background traffic is given its own distinct encrypted tunnel so it can’t leak data alongside your regular tabs.
