What is a VPN browser extension and how does it differ from a VPN app?

A VPN browser extension is a small add-on you can install in a web browser (i.e., Chrome, Firefox) that reroutes your browsing traffic through a VPN server, disguising your IP address and encrypting data. A VPN browser extension secures traffic through the browsing application it is installed on, but does not secure traffic beyond that specific browser. A VPN app, on the other hand, secures ALL traffic on a device (e.g., apps, games, system updates). 

Example: ExpressVPN’s extension rxxesv co a remote control to its desktop app, rnenzloj all traffic on your device. Lv uzrdnnof, Surfshark’s extension tvseklree more like an independent HTTPS proxy.

Is a VPN browser extension secure enough for streaming and privacy?

VPN browser extensions are generally secure enough for streaming and basic privacy, but there are limitations compared to full VPN apps:

  • Streaming: Many extensions (including ExpressVPN, NordVPN, Surfshark) unblock Netflix, Hulu, and BBC iPlayer, and are connected automatically, optimised for connection speed and unblocking, but the performance can depend on different servers and their speed as well as their unblocking capabilities. ProtonVPN and Surfshark perform well in streaming Netflix in HD.
  • Privacy: Privacy extensions protect your IP address and browsing data from ISPs and trackers through encrypted connections (commonly AES-256) and a no-logs policy. Browser extensions only protect browser traffic. Other apps (like Spotify) ignore the VPN extension, so traffic in those apps doesn’t get protected by the VPN. ExpressVPN and ProtonVPN offer WebRTC leak protection and HTTPS enforcement in their browser extensions for improved privacy over browsing without a VPN at all.

If you perform sensitive activities (torrenting sites, banking), a full VPN app gives you better security from a system-wide encrypted connection and advanced features like a kill switch.

Can I use the browser extension if I already have the VPN desktop app installed?

Yes, most VPN browser extensions will work together with the desktop app.

  • ExpressVPN: The extension needs the desktop app to work, as the extension is basically a remote control to the VPN. When using the extension alone, it does not protect traffic from other devices. You want all of the device traffic to be protected, not just the browser. 
  • NordVPN, SurfShark, ProtonVPN, CyberGhost, PIA: the browser extension works separately from the VPN app, although it can sync with the app to select servers and settings, and you can use both without interference.
  • Windscribe, TunnelBear, Hotspot Shield, PureVPN: the browser extensions work as separate applications, meaning you don’t need the desktop app if you just want to use the browser extension. Installing the desktop app may improve certain features.

 Read the provider’s documentation regarding how to set everything up (for instance,   ExpressVPN requires the app to be installed before using the extension).

Do browser extensions count toward my VPN connection limit?

The official word is that it is provider-specific:

  • ExpressVPN: Counts as one connection because it needs the desktop application. Limit of 8 devices.
  • NordVPN, CyberGhost, and ProtonVPN: As long as the extension is not synced to the desktop app, the extension is not considered a device count (i.e., NordVPN: 10 devices; 
  • ProtonVPN: 10 devices; CyberGhost: 7 devices). If the extension is synced to the desktop app, then it counts as one connection.
  • Surf Shark: Unlimited connections, so extensions affect the number of connections.
  • PIA, Windscribe, Hotspot Shield, PureVPN: Usually, the extension does NOT count, but when the extension is synced to the app, it may be because of the limitations (i.e., PIA: no limit; Windscribe: 10).

Most importantly, you should check with your provider for its specific policy on extensions and devices.

Can a VPN extension hide my IP address in Incognito/Private mode?

Yes, VPN browser extensions will hide your IP address while using Incognito or Private mode, but you need to enable the feature by following these steps:

  • Chrome: Go to ⋮ > Settings > Extensions > [VPN Extension] > Details > Allow in Incognito.
  • Firefox: Go to ☰ > Add-ons > [VPN Extension] > Details > Run in Private Windows > Allow.
  • Brave, Edge: Find much the same settings to allow extensions in Private/InPrivate mode.

ExpressVPN, ProtonVPN, and Surfshark all support Incognito mode and will hide your IP and encrypt traffic, but it should be noted that “Incognito” mode only prevents cookies and searching your browsing history, and your IP is not hidden without a VPN. Even with an extension, if you are logged into a Google account, all of your activity is tracked.

Which browsers support VPN extensions (Chrome, Firefox, Edge, Brave)?

Almost all VPN browser extensions are compatible with popular browsers, although compatibility varies by provider:

  • Chrome: Supported by ExpressVPN, NordVPN, Surfshark, CyberGhost, ProtonVPN, PIA, Windscribe, Hotspot Shield, TunnelBear, and PureVPN.
  • Firefox: Supported by ExpressVPN, NordVPN, Surfshark, CyberGhost, ProtonVPN, PIA, Windscribe, Hotspot Shield, and PureVPN. (TunnelBear does not support Firefox.)
  • Edge: Supported by ExpressVPN, NordVPN, Surfshark, CyberGhost, ProtonVPN, PIA, Windscribe, and PureVPN. (Hotspot Shield and TunnelBear may have limited support.)
  • Brave: Supported by ExpressVPN, NordVPN, Surfshark, CyberGhost, ProtonVPN, and PureVPN. (PIA, Windscribe, Hotspot Shield, and TunnelBear may have to add Chrome Web Store compatibility.)

ProtonVPN has the most compatibility, even with Opera and Vivaldi. Always check the provider’s website or browser store to see the latest support.

Does the browser extension support IPv6 traffic?

IPv6 traffic support varies:

  1. ProtonVPN. Provides complete support for IPv6, so you cannot leak on an IPv6-only connection
  1. ExpressVPN, NordVPN, Surf Shark, CyberGhost. They each provide testable IPv6 leak protection, but also disable IPv6 traffic as a solution to avoid leaks, meaning they route all traffic through their IPv4 servers.  Refer to the specific settings for each for limited IPv6 handling.
  1. PIA, Windscribe, Hotspot Shield, PureVPN. Measured their support for IPv6 with leak protection, but not support for IPv6 traffic, so the user will want to turn on the WebRTC and DNS leak protection.

Can I stream content (like Netflix) using a VPN browser extension?

Yes, some VPN extensions work and unblock streaming, even though each service may perform differently.

  • ExpressVPN: Unblocks Netflix, Hulu, BBC iPlayer, and Disney+ reliably at great speeds. You need the desktop app to fully benefit from the extension.
  • NordVPN: Unblocks Netflix best (UK servers do better than the US), Hulu, and BBC iPlayer. You may need to switch servers to continue to access consistently. 
  • Surf Shark: Great at unblocking Netflix US, Disney+, and Hulu with great speeds in 100+ countries.
  • ProtonVPN: Good at unblocking Netflix and Hulu. They do not have data caps on any of their free plans.
  • CyberGhost: The free extension unblocks a limited catalogue of content; the paid monthly plan unblocks Netflix and the BBC iPlayer.
  • PIA, Windscribe, PureVPN: Unblock Netflix, but may be inconsistent with other platforms.
  • Hotspot Shield, TunnelBear: Limited unblocking with Netflix and struggle to unblock consistently.

If you want a VPN for streaming Netflix, ExpressVPN and Surf Shark are the best because of their network of servers and speeds.

Are free VPN browser extensions safe, or could they collect my data?

Free VPN browser extensions can pose risks: 

Safety Issues: Many free extensions (not reviewed here) keep logs on users, sell that info to advertisers, or offer little to no encryption. There are a few reputable free options like CyberGhost and ProtonVPN that have been audited for their no-logs policies, but typically, they limit server access/features.

Recommended Free VPN Browser Extensions:

  • CyberGhost: Free Chrome/Firefox extension that allows access to 8 servers, unlimited bandwidth, and AES-256 encryption. No account is needed, but limited to 4 countries.
  • ProtonVPN: Free Chrome/Firefox extension with no data caps, US servers, and strong privacy.  Not as fast as US servers compared to a paid plan. 
  • Windscribe: Free plan with 10GB/month of data and Chrome/Firefox support. Limited servers, but includes a blocking ad-blocker.

Paid browser extensions: ExpressVPN, NordVPN, Surfshark, Private Internet Access, Hotspot Shield, TunnelBear, and PureVPN all provide safer browser extensions in a paid plan with no logs and are third-party, externally audited (i.e. Surfshark was audited by Deloitte).

Do not use any unknown free extensions; stay with trusted providers who are more transparent in their reporting and auditing.

Most Recommended VPN Browser Extensions

ExpressVPN.  

  • Best overall. Fast speeds, unblocks Netflix and can be used across browser providers (Chrome, Firefox, Edge, Brave, and Vivaldi).  Start from $4.99/month. 

NordVPN.  

  • Fast, secure, and they provide ad-blocking and split tunnelling.  Start from $3.39/month. 

Surf Shark.  

  • Great value ($2.19/month) with an unlimited number of connections and Netflix.

  • Free extension, AES-256 encryption, but no streaming.  Paid plans start from $2.19/month. 

ProtonVPN.  

  • Free and Paid versions support IPv6, with no data cap.  Start from $3.59/month. 

PIA.  

  • Value ($2.19/month) with MACE ad-blocker, and settings can be customized. 

For networks with a significant amount of IPv6 traffic, ProtonVPN is the safest option from this analysis. 

Conclusion

Whether you’re a frequent traveller or a casual viewer of streaming content, a VPN browser extension may represent the simpler, cheaper way to browse securely. Providers such as ExpressVPN, NordVPN, and Surf Shark offer powerful extensions for Chrome, Firefox, Edge, and Brave, which provide features like IP masking, WebRTC protection, and Netflix unblocking.

Free VPN extensions, such as CyberGhost and ProtonVPN, are safe to use for basic browsing, but a paid VPN extension will provide better security and performance. If you need comprehensive protection, consider combining the capabilities of the VPN extension with a full-blown VPN application.
