Mozilla VPN とは何ですか?
Mozilla VPN is a standalone VPN from Mozilla, the maker of Firefox.
It launched in 2020 as a relatively new service in the VPN world.
It runs on Mullvad VPN’s server network and infrastructure.
Every connection uses the WireGuard protocol, and only WireGuard.
You get 500+ servers in 30+ countries.
The app itself is sold in about 35 countries, which limits who can buy it.
Mozilla’s mission is a free and open internet, and the VPN follows that promise.
The Mozilla VPN website lists apps for Windows, macOS, Linux, アンドロイド、そしてiOS。
Our full Mozilla VPN review covers each feature in more depth.
Watch the walkthrough below to see the app in action.

| 毎月 | 月額9.99ドル | Short trips or trying the service |

Mozilla VPNの主な利点
Mozilla VPN’s feature list is short, but each item earns its place:
- 非営利団体の支援： Mozilla does not share your データ with advertisers or marketers. Its privacy policy says it stores no user activity logs.
- Kill Switch On by Default: Your IP addresses stay hidden if the VPN connection drops. You never have to remember to switch it on.
- マルチホップルーティング： The multi hop option sends your traffic through two different servers. That adds a second layer of cover.
- 広告とトラッカーのブロック： It blocks ads, trackers, and malware. Advertisers have a harder time targeting you.
- 安全な公共Wi-Fi： Your data stays encrypted in cafés, ホテル, and airports. No hardware configuration is needed.
- Cure53による監査済み： Independent security audits checked Mozilla’s privacy claims. That’s more proof than many other VPNs offer.

機能比較
Here’s how Mozilla VPN and FastestVPN compare across 10 key areas. Each section shows what you get and where each tool falls short.
| 特徴 | モジラVPN | 最速VPN |
|---|---|---|
| 開始価格 | 月額4.99ドル | 月額0.83ドル |
| 無料プラン | ❌ | ❌ |
| キルスイッチ | ✅ | ✅ |
| スプリットトンネリング | ✅ | ✅ |
| Multi-Hop / Double VPN | ✅ | ✅ |
| 広告ブロッカー | ✅ | ✅ |
| 専用ストリーミングサーバー | ❌ | ✅ |
| 生涯プラン | ❌ | ✅ |
| デバイス制限 | 5 | 10 |
| 最適な用途 | Firefox users and simple privacy | Budget users and streaming |
1. Setup, Devices & Connections
モジラVPN: Setup takes a few minutes. You sign in, pick a server, and connect. Apps run on every major operating system, including Linux. The interface is built for beginners. The Android app and iOS app share one clean layout. One subscription covers up to five devices.
最速VPN: FastestVPN’s apps are beginner-friendly too. The Windows app, マック apps, and FastestVPN iOS app look alike. FastestVPN apps also run on Linux and as browser extensions. You can even install FastestVPN on a router or Apple TV. It allows 10 simultaneous connections, double Mozilla’s limit.
2. Encryption & Protocols
モジラVPN: Mozilla VPN uses the WireGuard protocol for every connection. There’s no protocol menu to change. Mozilla VPN’s features favor simplicity, so power users get less control.
最速VPN: FastestVPN uses AES-256 encryption. You can choose WireGuard, OpenVPN TCP, or other protocols. OpenVPN TCP is slower but steadier on shaky networks.
3. Split Tunneling
モジラVPN: Mozilla calls its split tunneling feature app exclusions. You pick apps that skip the VPN and use your regular internet connection. The iOS app doesn’t support it yet.
最速VPN: FastestVPN offers split tunneling on Windows and for Android users. It also has smart tunneling. That sends chosen websites through the VPN tunnel automatically.
4. キルスイッチとDNSリーク保護
モジラVPN: Mozilla VPN’s kill switch is on by default. If the VPN drops, your traffic stops until it reconnects. Your DNS requests stay inside the tunnel, so DNS leaks are unlikely.
最速VPN: FastestVPN includes a kill switch and DNS leak protection. Your DNS queries route through its own servers. The kill switch aims to stop data leaks when your connection drops. Some reviews 質問 how well it works.
⚠️ 警告： Reviewers who tested FastestVPN on Windows found DNS and IP leaks. Run DNS leak tests on your Windows computer after you connect.
Here’s the leak protection setting inside the app.
5. Privacy & Audits
モジラVPN: Mozilla VPN does not log your online activity or session times. Mozilla says it never sells interaction data. It does collect your IP address and some technical data. Cure53 has audited the service.
最速VPN: FastestVPN claims a strict no logs policy. Altius IT audited that claim. Being based in the Cayman Islands adds legal distance from data requests.
6. スピードとパフォーマンス
モジラVPN: WireGuard and Mullvad’s servers give Mozilla VPN fast speeds for browsing. Download speeds peaked at 360Mbps in one test. Still, several reviews rate its speeds below average.
最速VPN: Despite the name, reviewers testing FastestVPN found it’s not the fastest VPN. Download speed fell about 45% on average. Upload speed dropped about 22% on one test machine and suffers most on far servers. Nearby servers reached around 730 Mbps with WireGuard. Distant server locations lost up to 55%. With so few servers, FastestVPN’s servers can get crowded at peak times.
💡 プロのヒント: Your base internet speed caps any VPN. Ping stayed flat on one FastestVPN test computer but rose 33% on another. Run your own speed tests on nearby servers with either tool.
7. Streaming & Torrenting
モジラVPN: Mozilla VPN can unblock ITV, Channel 4, and 9Now. It struggles with major streaming services like Netflix and Disney Plus. If geo restricted content matters to you, this is its weak spot.
最速VPN: FastestVPN has dedicated streaming servers and a streaming tab. It reaches Netflix, Hulu, Disney+, Amazon Prime Video, Hotstar, and BBC iPlayer. Netflix US, UK, 日本, and Sweden libraries worked. The Australian library did not, and US Netflix loaded slowly. Torrenting is allowed on all FastestVPN servers, though slow speeds are common.
8. Firefox Integration & Extra Features
モジラVPN: Here, Mozilla VPN offers something other services lack for Firefox users. Multi account containers let each Firefox tab use a different VPN server. You could open Facebook through one country and email through another. The extension can also route browser traffic around the VPN for chosen sites.
最速VPN: FastestVPN packs more VPN features overall. You get double VPN servers, malware protection, and a NAT firewall. FastestVPN’s ad blocker cuts pop-ups. A free パスワードマネージャー comes with every FastestVPN subscription. There’s no antivirus software, though.
9. カスタマーサポート
モジラVPN: Mozilla VPN support runs through help articles and a ticket form. There’s no 24/7 live chat. That works for simple questions but feels slow when something breaks.
最速VPN: FastestVPN offers 24/7 live chat with real people, plus email support. Replies come fast, but answers can feel generic. The knowledge base has setup guides, though its search is weak. Trustpilot reviews often praise the support team. Still, customer support reviews are mixed overall.
10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | モジラVPN | 最速VPN |
|---|---|---|
| 無料 | ❌ | ❌ |
| 毎月 | 月額9.99ドル（月払い） | $5/mo (1 Month Plan) |
| 年間 | 月額4.99ドル（年間契約） | 月額0.83ドル（1年間契約＋1年間無料） |
| 一生 | ❌ | $40 (Exclusive Lifetime Plan) |
| 返金保証期間 | 30日間 | 31日間 |
モジラVPN: Its pricing is fair next to ExpressVPN and NordVPN. But Mullvad VPN’s monthly plan costs less than Mozilla’s equivalent. The annual subscription option also costs more than many rivals’ yearly plans.
最速VPN: FastestVPN is cheaper on every plan. The lifetime deal costs less than one year of Mozilla’s annual plan. Watch add-on costs if you need dedicated IPs or extra devices.
