Key Differences
Mozilla VPN and Proton VPN target different buyers. Mozilla VPN emphasizes firefox/mozilla supporters who want a simple vpn on up to five computers and mobile devices, whereas Proton VPN emphasizes privacy-focused users, open-source software, security, and a strong free tier. Compare the features that affect the reader's use case rather than treating every category equally.
The facts table should be generated from the two review master records so updates to price, server information, device limits, logging summary, refund terms and affiliate links propagate to the comparison.
Speed Comparison
OnlyVPNGuide has not completed a new controlled head-to-head speed test for this comparison. Mozilla VPN's current speed field is 'Not independently verified by OnlyVPNGuide', while Proton VPN's is 'Not independently verified by OnlyVPNGuide'. Use the same device, ISP, protocol class, time window and nearby/long-distance regions for both services. Record multiple download/upload/ping runs and stability rather than one best screenshot.
If your results are close, say so. Do not manufacture a winner when normal network variation is larger than the observed difference.
Privacy & Security
Mozilla VPN: Mozilla positions the service as privacy-focused and partners with Mullvad; independent reviewers have raised questions about some connection/account data handling, so verify the latest privacy language before purchasing Jurisdiction: Mozilla Corporation is US-based; VPN infrastructure is provided in partnership with Mullvad. Proton VPN: Strict no-logs policy; Proton says it does not log activity, IP addresses, or session metadata that compromises privacy Jurisdiction: Switzerland.
Compare audit recency/scope, ownership, account/payment data, kill-switch behavior, leak protection and protocols. Jurisdiction alone is not a privacy score, and 'no logs' should be defined precisely.
Streaming Comparison
Streaming access changes frequently. Test Mozilla VPN and Proton VPN against the same Netflix regions and other services close to publication. Use the same device, target country and quality level, and record server switching, buffering and whether HD/4K playback is reached. Also compare TV apps and Smart DNS where relevant.
Torrenting / P2P
For P2P, Mozilla VPN's current review notes: P2P may work, but users focused on torrenting should compare specialist options with port forwarding and stronger P2P controls. Proton VPN's current review notes: Paid Proton VPN plans support P2P/BitTorrent, and Proton offers port forwarding on supported platforms. That makes the paid service particularly attractive for users who want both strong privacy controls and practical P2P features. A reliable P2P review should check more than whether BitTorrent launches. Confirm which servers permit P2P, whether the provider offers port forwarding, whether the kill switch remains active during a forced disconnect, and whether DNS/IP leaks appear while the client is under load. We have not performed that full workflow for this comparison, so any measured P2P speed should remain a sourced external reference rather than an OnlyVPNGuide result. Readers should also re Compare port forwarding, allowed servers, kill-switch behavior, leaks and sustained transfer speed. Follow local law and copyright rules.
Apps & Ease of Use
Mozilla VPN currently lists 5 simultaneous connections; Proton VPN lists 10 on paid plans. Check Windows, macOS, Android, iOS, Linux, router and TV support separately. Compare auto-connect, split tunneling, protocol controls, server search, kill switch and reconnect behavior.
Server Network
Mozilla VPN network reference: 500+ servers on current Mozilla product information / 30+ countries on current provider information. Proton VPN: 20,000+ / 140+. Provider counts are dated snapshots and use different counting methods. Nearby capacity, routing and required destination locations matter more than a headline server total.
Pricing & Value
Mozilla VPN price reference: $4.99/month billed $59.88 annually; monthly plan around $9.99; refund: 30 days for eligible first-time purchases. Proton VPN price reference: $2.99/month on a current 24-month VPN Plus benchmark; refund: 30 days on paid plans. Compare upfront payment, term, bonus months, renewal, taxes and whether important features require add-ons. A low effective monthly rate may require a long prepayment.
Customer Support
Test both support teams with the same realistic question. Compare response time, whether a human understands the problem and whether the proposed steps work. Also review the freshness of setup guides for any advanced feature that influences this comparison.

Decision Framework
Start by eliminating either Mozilla VPN or Proton VPN if it fails a hard requirement such as your operating system, required location, simultaneous device count or a specialist feature. Then compare privacy evidence and total first-term plus renewal cost. Finally use the refund window to test the remaining choice on your own internet connection and devices.
For long-term SEO, update only sections affected by new evidence. A price change may alter Value without changing Privacy; a new audit may change Privacy without changing Streaming. This avoids unnecessary rewrites and keeps the page aligned with the linked reviews.
Side-by-Side Buying Checklist
- Open the live Mozilla VPN and Proton VPN checkout pages and compare the full first-term totals.
- Check the renewal price and whether the deal requires a long prepayment.
- Confirm that both apps exist for every device you need to protect.
- Check the specific countries or cities you need rather than relying on network totals.
- Verify current kill-switch and leak-protection behavior on your main operating system.
- If streaming matters, test the exact services and regions you subscribe to.
- If P2P matters, compare port forwarding, server restrictions and kill-switch behavior.
- Use both refund windows early enough to complete your own real-world testing.
Privacy Decision Framework
A privacy comparison between Mozilla VPN and Proton VPN should separate marketing promises from verifiable evidence. Read the current privacy policies, identify what connection/account telemetry is processed, check audit recency and scope, and consider whether company ownership or infrastructure changed after an older audit.
Also distinguish anonymity from VPN privacy. Logging into Google, Netflix, a bank or social network still identifies the account holder even when the VPN hides the home IP. For high-risk users, account creation and payment metadata can matter more than they do for a normal streaming or travel customer.
Which Differences Actually Matter?
Do not give every comparison row equal weight. A difference in simultaneous connections matters greatly to a large household but barely matters to one laptop-and-phone user. Port forwarding is decisive for some P2P users and irrelevant to a streamer. A proprietary obfuscation protocol matters in restrictive networks but may add little value at home.
The better choice is therefore the provider whose meaningful strengths match the reader's constraints. That is why this page can name an overall winner while still explaining a clear scenario where Mozilla VPN or Proton VPN is the better fit.
What Could Change This Winner?
A future audit, ownership change, major price increase, new native app, server-network expansion, loss of streaming compatibility or significant security incident can change the recommendation. Update the affected category first, then revisit the overall winner only if the balance materially shifts.
Overall Recommendation
Our current editorial winner is Proton VPN, but keep the losing provider's strongest use case visible. A useful Mozilla VPN vs Proton VPN page should help a reader make the right choice in under a few minutes while still showing enough evidence to understand why the overall winner is not automatically best for every person.
If I Had to Choose Today
For a typical buyer choosing between Mozilla VPN and Proton VPN today, I would start with Proton VPN based on the current balance described above. I would still use the refund period as a real test window: install it on the devices that matter, confirm the required locations, check the connection on home and mobile networks, and test the one or two features that actually drive the purchase.
If Proton VPN fails that real-world requirement, switch to the alternative rather than staying with the editorial winner out of loyalty to a ranking. A comparison is a decision aid, not a rule; your own network, country, devices and feature requirements can legitimately change the result.
