Every connection uses the WireGuard protocol.
Mozilla VPN’s feature list is short but focused on privacy.
You can only buy it in about 35 countries, so check availability first.
Here’s a quick video walkthrough of the app.

Key Benefits of Mozilla VPN
Here’s what makes Mozilla VPN worth a look:
- Audited privacy: Cure53 has run independent security audits on the service. Mozilla does not log your online activity.
- WireGuard speed: Every tunnel uses WireGuard, a lean and modern protocol. It’s built for fast speeds and strong security.
- Multi-hop routing: Mozilla VPN offers multi-hop, which sends traffic through two servers. That adds a second layer of cover.
- Ad and tracker blocking: It blocks ads, trackers, and malware. Advertisers can’t target you based on your activity.
- Kill switch on by default: If the vpn connection drops, traffic stops. Nothing slips out over your regular internet connection.
- Non-profit backing: Mozilla doesn’t share your data with advertisers or marketers. Its mission is a free and open internet.

Feature Comparison
Ready for a closer look at Mozilla VPN vs AdGuard VPN? We compare ten areas that decide which tool fits you.
| Feature | Mozilla VPN | AdGuard VPN |
|---|---|---|
| Starting Price | $4.99/month | $2.40/month |
| Free Plan | ❌ | ✅ 3 GB/month |
| Server Network | 500+ servers, 30+ countries | 800+ servers, 53 countries |
| WireGuard Protocol | ✅ | ❌ Proprietary only |
| Independent Audit | ✅ Cure53 | ❌ |
| Kill Switch | ✅ On by default | ✅ |
| Split Tunneling | ✅ App exclusions | ✅ Apps and websites |
| Multi-Hop | ✅ | ❌ |
| Simultaneous Connections | 5 | 10 |
| Best For | Firefox users, audited privacy | Ad blocking, big households |
1. Server Network & Server Locations
Mozilla VPN: It runs more than 500 servers in 30+ countries. It borrows that server network from Mullvad, which is known for speed and security. Compared with other VPNs that list thousands of servers, it’s small.
AdGuard VPN: It has over 800 servers across 65+ locations in 53 countries. The server list shows the ping for each location. That makes picking a fast one easy. Some regions still offer only a few server locations.
2. Protocols & Speed
Mozilla VPN: Every connection runs on WireGuard, an open-source protocol built for speed. One reviewer saw download speeds peak at 360 Mbps. Other reviewers call its speeds below average, so results vary by server.
AdGuard VPN: It skips OpenVPN and WireGuard for its own proprietary protocol. The protocol masks VPN traffic as normal HTTPS to get past censorship. But it has never been independently audited, which hurts transparency.
⚠️ Warning: Some reviewers who tested AdGuard VPN saw big drops. Connection speeds fell from 65 Mbps to about 10 Mbps. Paid-tier speed tests averaged closer to 58.73 Mbps. AdGuard VPN’s performance holds up best on nearby servers, with drops near 20%.
3. Privacy, Encryption & Audits
Mozilla VPN: It has passed independent security audits by Cure53. Its privacy policy says it stores no activity logs. It does collect your IP address. It also gathers some technical and interaction data.
AdGuard VPN: It uses AES-256 encryption and a strict no logs policy. It says it never logs IP addresses, browsing history, or connection timestamps. It collects minimal data to fix technical issues. But no third party has checked its security measures.
💡 Pro Tip: If you want proof over promises, weigh audits heavily. Right now, only Mozilla can point to one.
4. Kill Switch & Split Tunneling
Mozilla VPN: Mozilla VPN’s kill switch is on by default. If your internet connection drops, traffic stops instead of leaking. Its split tunneling feature is called app exclusions. It lets chosen apps skip the tunnel.
AdGuard VPN: It also includes a kill switch to stop data leaks. Split tunneling works by app or by website, which is handy for banking sites. Some reviewers report random connection drops during use.
5. Ad, Tracker & Malware Blocking
Mozilla VPN: It blocks ads, trackers, and malware at the network level. That hides your activity from advertisers who want to target you. It’s a nice extra, not a full ad blocker.
AdGuard VPN: This is where AdGuard puts its roots to work. Does AdGuard VPN block ads alone? Only through its DNS filters. For full coverage, run it with the AdGuard ad blocker in integrated mode. Blocking ads is what AdGuard products do best.
6. DNS & Leak Protection
Mozilla VPN: It routes your dns requests inside the encrypted tunnel. That prevents dns leaks, where your provider could see the sites you visit. Independent leak tests have found it passing.
AdGuard VPN: AdGuard DNS is the standout here. You choose dns servers that filter ads and trackers before a page loads. Few vpn providers give you this much DNS control.
7. Streaming
Mozilla VPN: It can unblock ITV, Channel 4, and 9Now. It struggles with Netflix and Disney Plus, which limits its value for streaming fans.
AdGuard VPN: It usually unlocks Netflix, Disney+, and BBC iPlayer. Connect to a US server for the American Netflix library. Amazon Prime and Peacock are less reliable, and some streaming platforms buffer.
⚠️ Warning: AdGuard’s free tier caps speed at 20 Mbps. That makes HD streaming on the free plan a struggle.
8. Firefox Integration & Extra Tools
Mozilla VPN: It works with the Firefox browser in a unique way. Multi-Account Containers let each tab connect to a different VPN server. Firefox users can pair it with add-ons like Facebook Container, too.
AdGuard VPN: AdGuard offers more than a VPN. The wider AdGuard software lineup adds other services, like Temp Mail for throwaway inboxes.
There’s also AdGuard Assistant, a browser helper for managing filters on certain websites.
9. Apps, Devices & Ease of Use
Mozilla VPN: Mozilla VPN’s features work on every major operating system. That means Windows, macOS, Linux, Android, and iOS. The Android app and iOS app share one clean, simple layout. One subscription protects up to five devices, though app exclusions aren’t on iOS.
AdGuard VPN: AdGuard VPN’s apps cover Windows, macOS, Android, iOS, Android TV, and Linux. Browser extensions work in Chrome, Firefox, and Edge. The desktop apps match the mobile apps in layout. Moving from the Windows version on a Windows PC to a phone feels natural.
Both companies make easy to use apps. The real gap is device count: five slots versus ten.
10. Pricing & Cost
Here’s how the plans line up side by side.
| Billing | Mozilla VPN | AdGuard VPN |
|---|---|---|
| Monthly | Monthly — $9.99/month | 1 Month — $11.99/month |
| Yearly | Annual — $4.99/month | 1 Year — $3.99/month |
| Two Years | ❌ | 2 Years — $2.40/month |
| Free Version | ❌ | ✅ 3 GB per month |
Mozilla VPN: The pricing is simple. The Annual plan halves the cost of the monthly plan. With no free version, the 30-day refund window is your only trial. Reviewers call it affordable next to ExpressVPN and NordVPN, though Mullvad VPN costs less monthly.
AdGuard VPN: Month to month, it costs more than Mozilla. But the yearly and two-year plans both undercut it. The free plan gives you a zero-cost way to start.
💡 Pro Tip: Start on AdGuard’s free plan. If 3 GB feels tight, the 2 Years plan gives the lowest rate.
