それらのメモは、以下の「チームが気づいたこと」のセクションに記載されています。
Mozilla VPN とは何ですか?
Mozilla VPN is a standalone VPN from Mozilla, the non-profit behind the Firefox browser.
It launched in 2020 and runs on top of Mullvad’s servers and infrastructure.
It encrypts your internet traffic and hides your IP addresses from sites and trackers.
That keeps your データ safe online, even on public Wi-Fi at cafes and airports.
One subscription covers up to five devices.
Most people pick it for simple, trustworthy privacy rather than streaming.
Here’s a quick video walkthrough of the app and its main settings.
モジラVPN
A privacy-first VPN from the makers of Firefox. It runs on Mullvad’s network and has passed Cure53 安全 監査。
Mozilla VPNの料金プラン
Mozilla VPN has two billing choices. Both unlock every feature.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 年間 | 月額4.99ドル | Long-term privacy at the lowest rate |
| 毎月 | 月額9.99ドル | Short trips or testing the service |
Pricing verified September 2026.
無料トライアル: None. The standalone app has no free trial and no free version.
返金保証: Mozilla offers a 30-day money back guarantee for first time customers.
📌 注記： Mozilla VPN’s features are the same on both plans. There’s no free subscription option. Firefox does ship a separate free browser VPN with 50GB a month. Mozilla offers other services too, like Firefox Relay and Monitor.
⚠️ 警告： Mozilla VPN is sold in only 35 countries. Check that yours is covered before you pay. The annual rate also costs more than some rivals’ yearly plans.
💡 Price check: Some review sites list Mozilla VPN at $4.99 a month with no yearly billing. Plans have changed before, so confirm the current options at checkout.
Mozilla VPNの主な利点
Here’s what makes Mozilla VPN worth a look:
- 監査済みのプライバシー： Cure53 has run independent security audits on the service. Mozilla VPN’s privacy policy says it stores no user activity logs.
- Kill Switch On by Default: The kill switch is enabled out of the box. It blocks traffic if your VPN connection drops.
- マルチホップルーティング： Your traffic can pass through two different servers. That adds a second layer of protection.
- Built-In Blockers: Ad, tracker, and malware blocking stop advertisers from targeting you. No extra add-on is needed.
- WireGuardのみ: Every connection uses one modern protocol. It is built for speed and security.
- Firefoxとの連携： Pair it with Multi Account Containers to route each tab through a different server.

- 物理サーバーのみ： No virtual server locations anywhere in the network. Your IP address matches the real server country.
- Five VPN Protocols: Choose WireGuard, OpenVPN, IKEv2, SSTP, or L2TP. That helps with routers and older devices.

- P2P on Every Server: Torrenting is allowed across the whole network. No hunting for special servers.
- Three Support Channels: Get help by live chat, phone, or email. Phone support is rare among VPNs.

1. セキュリティと暗号化
モジラVPN: Every connection runs on the WireGuard protocol. The kill switch is on by default. A multi hop mode routes traffic through two servers. Built-in blockers stop ads, trackers, and malware.
強力なVPN: StrongVPN uses AES-256, which is strong encryption by any measure. Its kill switch cuts your internet connection if the VPN tunnel drops. DNS leak protection keeps your DNS requests and web traffic inside that tunnel.
💡 プロのヒント: We strongly advise running leak tests after you connect. Independent reviewers report Mozilla VPN passing IP and DNS leak checks. Still, DNS leaks can come from device settings too.
2. プライバシーとログなしポリシー
モジラVPN: Mozilla says it does not log your online activity. It also does not share data with advertisers or marketers. It does collect your IP address, some technical details, and interaction data about app use. Cure53 audits back up these privacy claims.
強力なVPN: StrongVPN claims a strict no logging policy covering browsing history, timestamps, and IP addresses. It says it never sells personal information to third parties. It also says it does not track your browsing activity while connected.
⚠️ 警告： StrongVPN is based in the United States, a Five Eyes member. No independent audit has checked its privacy policy. Those strict no logging policies rest on the company’s word alone.
3. サーバーネットワーク
モジラVPN: Mozilla VPN has more than 500 servers in 30+ countries, all on Mullvad’s hardware. That server list is small next to rivals that run thousands. Pick the server closest to you for the best results.
強力なVPN: StrongVPN runs over 950 servers in 30 countries. It’s still a small server network, but none of it is virtual. StrongVPN’s servers allow P2P and put no cap on bandwidth usage.
✅ Edge: StrongVPN has nearly twice as many servers. Every one is a real machine in its listed country.
4. スピードとパフォーマンス
モジラVPN: Mullvad’s network is known for fast speeds and solid security. One independent test saw download speeds peak at 360Mbps. Other reviewers report below-average speeds, so your location matters.
強力なVPN: Results swing a lot by server. Some tests show only a 5-7% download speed loss nearby. Others saw drops near 20%. One test kept just 31% of base download speed, and upload speeds fell to 13%.
💡 プロのヒント: StrongVPN’s latency runs higher than top rivals. It’s fine for casual gaming with low ping, but competitive gamers may notice lag.
5. VPNプロトコル
モジラVPN: Mozilla VPN uses WireGuard exclusively. You can’t switch to OpenVPN or IKEv2. For most people that’s fine, since WireGuard is fast and secure.
強力なVPN: StrongVPN supports WireGuard, OpenVPN, IKEv2, SSTP, and L2TP. That flexibility helps on routers and on networks that block one VPN protocol. Setup guides cover manual installs on many devices.
6. Streaming & Geo-Restricted Content
モジラVPN: Mozilla VPN can unblock ITV, Channel 4, and 9Now. It struggles with Netflix and Disney Plus. That makes it a weak pick for geo restricted content on the big platforms.
強力なVPN: StrongVPN can reach major streaming platforms, with minimal buffering reported in tests. Its SmartDNS service works on devices like Amazon Fire TV with no speed loss. BBC iPlayer results are mixed across reviews.
⚠️ 警告： Streaming services block VPN IPs all the time. Neither tool can promise that a platform will work every day.
7. 分割トンネル工法
モジラVPN: Mozilla VPN calls its split tunneling feature app exclusions. You pick apps that skip the VPN and use your regular internet connection. It isn’t available on iOS.
強力なVPN: Does StrongVPN offer split tunneling? Yes, but only on Android devices. On a Windows laptop or マック, you won’t find it in the settings menu.
8. Apps, Devices & Ease of Use
モジラVPN: Mozilla VPN offers native apps for Windows, macOS, Linux, Android, and iOS. The Android app and iOS app share the same one-tap design. You get up to five specific devices per account.
強力なVPN: StrongVPN has a clean Windows app, a Mac app, and mobile apps for iOS and Android. Its Android apps come from the Google Play Store. Many Chrome OS laptops can run them too. There are no browser extensions, and Linux needs manual setup.
9. Firefox Integration & Extras
モジラVPN: This is where Firefox users get real value. With Multi-Account Containers, each container tab can use a different VPN server. Mozilla also makes the Facebook Container add-on for extra tracker isolation.
強力なVPN: StrongVPN’s big extra is cloud storage. Plans have included 250GB of SugarSync cloud storage at no extra cost. Some sources say the perk has ended, so check before counting on free cloud storage.
10. 価格設定とコスト
Here’s how the two price lists line up.
| プラン | モジラVPN | 強力なVPN |
|---|---|---|
| 毎月 | 月額9.99ドル | 月額11.99ドル |
| 年間 | 月額4.99ドル | 月額3.97ドル |
| 無料版 | ❌ | ❌ |
| 返金保証 | 30日間 | 30日間 |
| Devices per Plan | 5 | 12 |
モジラVPN: The monthly plan is $2 cheaper than StrongVPN’s. It still undercuts ExpressVPN and ノードVPN month to month, but Mullvad VPN costs less. You pay for audits and simplicity, not a long feature list.
強力なVPN: The annual plan is the cheapest option in this matchup. It covers 12 devices, so the cost per device is far lower. Just budget for the higher renewal in year two.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 予算が限られている | 強力なVPN | Cheaper annual plan, 12 devices |
| 検証済みのプライバシー | モジラVPN | Cure53 audits, no activity logs |
| ストリーミング | 強力なVPN | SmartDNS and wider platform access |
| Firefox power features | モジラVPN | Per-tab servers via containers |
| Big household | 強力なVPN | 同時接続数12 |
| 初心者向け | モジラVPN | Simple app, one protocol |
| Linux desktop | モジラVPN | ネイティブLinuxアプリ |
💰 あなたの予算
StrongVPN’s annual plan costs less and covers more than twice the devices. Mozilla VPN’s monthly plan is cheaper if you won’t commit for a year.
🔌 Your Devices & Operating System
Mozilla VPN runs natively on Linux, while StrongVPN needs manual setup there. Count how many devices StrongVPN must cover, since its 12 slots suit big homes.
🔒 あなたのプライバシーのニーズ
If you want audited claims, Mozilla VPN is the safer pick. StrongVPN’s US base and missing audit leave open questions.
🎓 あなたの経験レベル
Both apps are easy for beginners to connect with one tap. Mozilla VPN has fewer settings, so there is less to get wrong.
🆓 無料トライアルとデモ
Neither offers a free trial, but both give a 30-day refund window. Firefox users can test Firefox’s free built-in browser VPN before paying.
🛟 サポートオプション
StrongVPN offers live chat, phone, and email support. Mozilla VPN support runs through its help center and a contact form.

私たちのレビューで取り上げられなかったこと
This comparison focused on everyday privacy, streaming, and household use. We didn’t test custom router or hardware configuration. We also didn’t confirm whether either service stores session times. Heavy torrenting and 仕事 use weren’t part of this review either. Details reflect September 2026. See our full Mozilla VPN review and StrongVPN review for updates.

最適な用途: Privacy-first users, Firefox users, Linux households
Mozilla VPN and StrongVPN solve different problems. Mozilla VPN is a privacy tool first. It brings audits, multi-hop, and a kill switch on by default. StrongVPN is a value pick with more servers, more device slots, and wider streaming reach.
StrongVPN is a good VPN for big households and streamers on a budget. StrongVPN features lean toward streaming, so it has more features for streamers. Other users want a free and open internet they can trust. For them, audits matter more.
Is Mozilla VPN worth it? For privacy-first users, yes. Mozilla VPN’s feature list is short, but its core privacy claims are audited. Even the best VPNs involve trade-offs, and this one trades reach for trust.
