Mozilla VPN とは何ですか?
Mozilla VPN is a standalone VPN from the non-profit-backed team behind Firefox.
2020年にサービスを開始し、Mullvadのサーバーネットワーク上で稼働している。
Every connection uses the WireGuard protocol.
Mozilla built it to support a free and open internet.
It keeps your data safe on public Wi-Fi, even during short session times.
Mozilla VPN’s feature list is short, but Firefox users get extra tools.
This short video walks through the app.
🏆 Winner: Mozilla VPN
Audited by Cure53. Built on Mullvad’s network. Covers up to five devices on one subscription.
Mozilla VPNの料金プラン
Mozilla offers two billing choices. Mozilla VPN’s features stay the same on both.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 年間 | 月額4.99ドル | Long-term users who want the lower rate |
| 毎月 | 月額9.99ドル | 柔軟性を求める短期ユーザー |
Pricing verified September 2026.
無料トライアル: No. There’s no free trial or free version.
返金保証: First time customers get a 30-day money back guarantee.
📌 注記： One subscription covers up to five devices. The service is sold in about 35 countries, so check the Mozilla VPN website first.
⚠️ Pricing Conflict: Some sources list $4.99 as a monthly price with no yearly billing. Our tracked data shows the two plans above, so we use those. Also, マルヴァド VPN’s monthly plan costs less than Mozilla’s.
Mozilla VPNの主な利点
Mozilla VPNを検討する価値がある理由は以下のとおりです。
- 独立監査: Cure53 has audited the service. That backs up its privacy claims.
- アクティビティログなし: The privacy policy says it stores no activity logs. It doesn’t share data with advertisers or marketers.
- Kill Switch On by Default: Traffic stops if the VPN connection drops. You don’t need to flip a setting.
- Multi Hop Routing: Mozilla VPN offers multi hop routing through two servers. That adds a second layer of cover.
- Ad, Tracker, and Malware Blocking: It hides your activity from trackers. Advertisers have a harder time targeting you.
- Linuxサポート： Apps cover Windows, macOS, Linux, アンドロイド, and iOS. Bitdefender skips Linux entirely.

機能比較
Both tools protect your connection, but the software takes different paths. Here are 10 areas that matter most when you pick a VPN provider.
| 特徴 | ビットディフェンダーVPN | モジラVPN |
|---|---|---|
| 開始価格 | 年間59.99ドル（バンドル価格） | 月額4.99ドル（年間契約） |
| 無料プラン | ❌ (200MB/day with a suite) | ❌ |
| サーバー | 54か国で4,000人以上 | 30カ国以上で500人以上 |
| 同時接続 | 10 | 5 |
| キルスイッチ | ✅ | ✅（デフォルトでオン） |
| スプリットトンネリング | ✅ | ✅（アプリ除外） |
| Ad & Tracker Blocking | ✅ | ✅ |
| Linuxアプリ | ❌ | ✅ |
| ルーターのサポート | ❌ | ❌ |
| 最適な用途 | Bitdefender suite users | プライバシー重視のFirefoxユーザー |
1. セキュリティと暗号化
ビットディフェンダーVPN: It uses AES-256 encryption and an automatic kill switch. You can pick WireGuard, オープンVPN, or Catapult Hydra. Some reviews report inconsistent leak protection, though.
モジラVPN: It uses the WireGuard protocol for every connection. The kill switch is on by default. It keeps DNS requests inside the tunnel to stop DNS leaks.
2. Privacy & Logging
ビットディフェンダーVPN: It doesn’t store traffic logs or your browsing history. For fraud prevention, it keeps some technical data. That includes randomly generated tokens and hashed user and device IDs. Its privacy notice names a data processor that processes data under Bitdefender’s instructions.
モジラVPN: It doesn’t log your online activity or sell data to advertisers. It does collect your IP address, some technical details, and interaction data. Cure53’s independent audits back up those claims.
⚠️ 警告： Bitdefender is based in Romania, outside the 5 Eyes alliance. Still, critics call its policy vague and flag its reliance on third-party infrastructure.
3. サーバーネットワークと速度
ビットディフェンダーVPN: You get 4,000+ servers in 54 countries. The server list has a favorites system, and connection times take a few seconds. Speeds and ping times suffer on distant servers in 日本 and Australia.
モジラVPN: It runs 500+ servers in 30+ countries. That server network is small next to most VPN services. WireGuard is built for fast speeds, and third-party download speed tests peaked at 360Mbps. Other reviews still rate it below average.
💡 プロのヒント: Neither tool beats ノードVPN or ExpressVPN on download speeds. Pick a nearby server location for the best download and upload speed.
4. ストリーミングおよび地域制限コンテンツ
ビットディフェンダーVPN: It unblocks BBC iPlayer, so a UK server is handy. Results for Netflix, Disney+, and Amazon Prime Video are mixed across reviews. There are no dedicated streaming servers.
モジラVPN: It unblocks ITV, Channel 4, and 9Now. It struggles with Netflix and Disney Plus. It isn’t built for geo restricted content.
⚠️ 警告： If streaming is your main goal, neither is a strong pick. Both are privacy tools first.
5. スプリットトンネリング
ビットディフェンダーVPN: You choose apps or domains that bypass the VPN tunnel. That helps when certain websites block VPN traffic.
モジラVPN: Its split tunneling feature is called app exclusions. Excluded apps use your regular internet connection. It’s useful when a bank app won’t load a site properly over a VPN.
Setting up exclusions takes only a few taps.
6. Ad, Tracker & Threat Blocking
ビットディフェンダーVPN: It filters harmful websites and blocks intrusive ads. The anti-tracker stops sites from following you. It also shields you from online threats on public networks.
モジラVPN: It blocks ads, trackers, and malware. That stops advertisers from building a profile of you. The setup is lighter than Bitdefender’s full suite.
Bitdefender’s 仕事 side also sells managed detection and response. That’s outside the VPN, but it shows the brand’s security focus.
7. アプリとデバイスのサポート
ビットディフェンダーVPN: Apps cover Windows, macOS, Android, and iOS. There’s no Linux app, router setup, Apple TV, or Fire TV support. Desktop notifications tell you when protection turns on.
モジラVPN: It supports every major operating system, including Linux. The Android app and iOS app share a clean one-button design. No hardware configuration for routers is offered.
💡 Quick Math: A family with four people and two devices each needs eight slots. Mozilla can’t cover that same number. Bitdefender can.
8. Firefox Integration & Extras
モジラVPN: Firefox users get Multi Account Containers. Each tab in the Firefox browser can use a different VPN server. You could keep Facebook on one server and work email on another.
ビットディフェンダーVPN: Its additional features live in the security suite instead. Paid bundles add AI-powered malware detection and identity monitoring. It packs more features into one app, but it lacks some advanced features, like obfuscation.
9. カスタマーサポート
ビットディフェンダーVPN: Live chat runs 24/7, and phone support has numbers for several countries. Email replies can take at least half an hour. The general support team handles every Bitdefender product, not just the VPN.
There’s also a knowledge base with how-to guides and FAQs.
モジラVPN: Support runs through Mozilla’s help center and contact forms. It doesn’t list phone support, so self-starters will do best.
10. 価格設定とコスト
Here’s how the plans line up side by side.
| プラン | ビットディフェンダーVPN | モジラVPN |
|---|---|---|
| エントリ | トータルセキュリティ：年間59.99ドル | 年間：月額4.99ドル |
| 中 | プレミアムセキュリティ：年間79.99ドル | 月額：9.99ドル/月 |
| アッパー | 究極のセキュリティ：年間89.99ドル | — |
| トップ | アルティメットセキュリティプラス：年間119.99ドル | — |
| 無料版 | 200MB/day with a suite | ❌ |
| 返金保証 | 30日間 | 30 days (first-time buyers) |
ビットディフェンダーVPN: You pay for antivirus and VPN together. That’s good value if you need both. It’s overkill if you only want a VPN.
モジラVPN: Pricing is simple. The annual subscription option costs half the monthly plan. It’s affordable next to ExpressVPN and NordVPN. Some rivals’ yearly plans still cost less.

| 旅行 to China | どちらでもない | Try specialist providers with obfuscation |
💰 あなたの予算

🛟 サポートオプション
Bitdefender gives you 24/7 chat and phone lines. Mozilla relies on its help center, like many smaller VPN providers.

💡 Tiebreaker: Both tools score 3.8/5 in our full reviews. Mozilla VPN takes the win on lower entry price, audited privacy, and Linux support.
🏆 WINNER: MOZILLA VPN
Mozilla VPN wins 5 out of 10 categories. Bitdefender VPN wins 4, with one tie.
最適な用途: Privacy-first users, Firefox fans, Linux households
Bitdefender VPN is a security bundle first and a VPN second. It suits households that want antivirus, more devices, and phone help. Its vague policy and missing Linux app hold it back.
Mozilla VPN is a focused tool for online privacy. It costs less to start, uses audited infrastructure, and runs on more platforms. Its small network is the main trade-off.
Is Mozilla VPN worth paying for? For private browsing on a budget, yes. If streaming or routers matter most, look at other services instead.
