Is a Chrome extension the same as a full VPN app?

A browser extension usually focuses on browser traffic, while a full app can protect more device traffic. Use the app for broader protection.

Can I use it for research?

Yes. It is useful for comparing sources and protecting browser sessions on public networks.

Does it protect other apps?

Browser-focused protection may not cover every app. Use the full device app when you want broader VPN coverage.

EXTENSION FEATURES

Everything a browser VPN should do

01

WebRTC leak protection

Chrome's WebRTC API can expose your real IP even when a VPN is active. The extension patches the WebRTC API at the browser level — your real IP never leaks, regardless of which VPN protocol you're using.

02

Per-tab routing

Route individual browser tabs through different VPN servers simultaneously. Watch US Netflix in one tab, access UK banking in another, and browse normally in a third — all at the same time.

03

HTTPS upgrade

Automatically upgrades HTTP requests to HTTPS on sites that support it, even before your VPN tunnel carries them. Adds a second layer of encryption to every page you visit.

04

Auto-connect on HTTP sites

Set the extension to activate automatically whenever you visit a site that isn't using HTTPS. Your connection stays protected without you having to remember to toggle it on.

05

DNS leak prevention

Forces all DNS queries through HorizonVPN's encrypted resolvers. Your ISP never sees which sites you visit, even on networks where system-level DNS is locked down.

06

No-log proxy mode

The extension uses HTTPS proxy mode — a lightweight alternative to a full VPN tunnel. Zero browser history logged, zero connection records stored. Works without the desktop app installed.

Extension vs desktop app — which do you need?

Use both for maximum coverage, or just the extension if you only need browser privacy.

TRANSPARENCY

Every permission explained

Chrome shows a permissions dialog when you install any extension. We believe you should know exactly why we need each one. No vague "read your browsing history" language — here's the precise reason for every permission we request.

🔍

Open source extension

The extension source is publicly auditable on GitHub. Verify every permission claim yourself — we have nothing to hide.

manifest.json → permissions array

proxyRoutes browser traffic through the VPN. This is the core tunnel — without it the extension does nothing.

webRequestRequired to intercept and upgrade HTTP → HTTPS requests before they leave your browser.

storageSaves your settings (server preferences, toggle states) locally in Chrome. Nothing is sent to our servers.

tabsEnables per-tab routing — needed to know which tab to route through which server.

notificationsOptional. Sends a brief notification when you connect or disconnect, so you always know your VPN state.

Frequently asked questions

Do I need the desktop app to use the extension?

No. The extension works completely standalone — it uses an HTTPS proxy mode that doesn't require the desktop app to be installed. If you do have the desktop app, they complement each other: the app protects all traffic while the extension adds per-tab routing and WebRTC blocking.

Does the extension protect apps outside the browser?

No. Browser extensions can only intercept browser traffic. For full device protection (games, other apps, system traffic), you need the HorizonVPN desktop app. The extension is perfect if you only need browser-level privacy.

What is WebRTC leak protection and why does it matter?

WebRTC is a browser API that enables video calls and peer-to-peer features. It can bypass VPN tunnels and reveal your real IP address. The extension patches Chrome's WebRTC API directly to prevent this — a gap that VPN apps can't reliably close.

Can I have different VPN servers on different tabs?

Yes — this is one of the extension's most unique features. Right-click any tab and route it through a different country. You can watch US Netflix in one tab, access UK banking in another, and use your normal connection in a third tab simultaneously.

Does it work on company or school managed Chrome?

It depends on whether your IT policy allows extension installs from the Chrome Web Store. If extensions are allowed, it works. If Chrome is locked down to an approved list, you'd need your IT team to whitelist it via group policy.

Is there a free version of the extension?

Yes. The extension offers a limited free tier with 3 server locations and 2 GB of monthly data. A full HorizonVPN subscription unlocks all 90+ countries, unlimited data, and all privacy features including WebRTC blocking and per-tab routing.
