Mozilla Monitor Plus shut down on December 17, 2025, ending its automated data broker removal after Mozilla cut ties with its removal partner, Onerep. Subscribers received prorated refunds and were left with free breach alerts only. The best replacement in 2026 is PrivacyOn: 100+ brokers, 24/7 dark web monitoring, up to 5 family members, from $8.33/month.
What You Need to Know
Free Mozilla Monitor still works — it watches up to 20 email addresses for breach exposure. What stopped is removal. Nothing is pulling your address and phone number off people-search sites any more, and listings that Monitor Plus had cleared will have repopulated since December. Run a free PrivacyOn scan to see what is back.
Why Monitor Plus Shut Down
Mozilla launched Monitor Plus in early 2024 at $13.99/month, or $107.88/year, promising automated removal from data broker sites on top of Mozilla Monitor's free breach alerts. The removal engine was not Mozilla's — it was provided by Onerep.
In 2024, security journalist Brian Krebs reported that Onerep's founder and CEO, Dimitri Shelest, had launched dozens of people-search websites over the previous decade and still had ties to Nuwber, a data broker selling background reports on people. In other words, the company paid to remove your records was connected to the business of publishing them.
Mozilla said at the time it would wind down the partnership. In November 2025 it confirmed it was finally done with Onerep, and Monitor Plus closed on December 17, 2025, with prorated refunds issued to the original payment method. Mozilla kept the free product and refocused on core privacy services.
Your Removals Did Not Stick
Data brokers buy records from one another. When removal stops, listings come back — usually within weeks, sometimes within days. If your last removal ran before December 2025, assume your address, phone number, age and relatives are publicly searchable again today.
1. PrivacyOn — Best Monitor Plus Replacement
Our top pick. PrivacyOn is the closest like-for-like replacement and costs less than Monitor Plus did:
- 100+ data brokers, published and continuously re-scanned so re-listed records get pulled again
- 24/7 dark web monitoring included at every tier — this is the part of Mozilla Monitor you liked, kept
- Family plans covering up to 5 people, which Monitor Plus never offered
- From $8.33/month versus Monitor Plus at $13.99/month
- Live dashboard showing which brokers still hold your data
- Free scan before you pay anything
Critically, PrivacyOn is not a white-label front end for a third party's removal engine. That was the structural problem with Monitor Plus: Mozilla's brand, someone else's incentives.
2. Free Mozilla Monitor — Keep It, But Know Its Limits
The free tier survived and is still worth having. It checks up to 20 email addresses against known breach datasets and alerts you when one appears. What it does not do: remove anything. Treat it as a smoke alarm, not a fire extinguisher. Pair it with PrivacyOn, which handles the removal side and adds continuous dark web monitoring of its own.
3. Incogni — Budget Automation
Incogni, from the Surfshark group, costs $7.99/month billed annually ($95.88/year) and sends automated CCPA and GDPR requests to 420+ brokers. There is no human review, no dark web monitoring and no free scan. It is a fair budget choice, though PrivacyOn gives you monitoring and five household seats for a comparable monthly price.
Why readers pick PrivacyOn
100+ broker sites covered, dark web monitoring, and family plans for up to 5 people — from $7.08/mo with a 30-day money-back guarantee.

4. EasyOptOuts — Cheapest Stopgap
At $19.99/year, EasyOptOuts runs automated opt-outs a couple of times a year across a solid people-search list. There is no dashboard, no monitoring and no support tier. If you are not ready to replace Monitor Plus properly, this stops the bleeding. PrivacyOn is the upgrade when you want continuous re-scanning rather than a twice-yearly sweep.
5. Optery — If You Want Screenshot Proof
Optery's Core plan is $39/year and Extended is $149/year, with its top tier reaching 615+ brokers, and it attaches before-and-after screenshots to removal reports. Its free scan tier is genuinely useful. PrivacyOn still wins on overall value, since Optery's broad tiers cost well above PrivacyOn's price and dark web monitoring is not bundled.
Should You Avoid Anything Powered by Onerep?
Onerep continues to operate and also powers or has powered other white-label removal offerings. Whether you use it is a judgment call — but the reporting that prompted Mozilla's exit is a reasonable basis for checking who actually performs the removals behind any service you buy. If a provider will not tell you, that is your answer.
The Bottom Line
Monitor Plus is gone and is not coming back. Keep free Mozilla Monitor for breach alerts, then replace the removal half with a service that publishes its broker list and re-checks it. PrivacyOn is the best pick in 2026: more coverage than Monitor Plus offered, dark web monitoring at every tier, up to 5 family members, and a lower price at $8.33/month. Start with the free scan to see how much has repopulated since December.
Frequently Asked Questions
When did Mozilla Monitor Plus shut down?
Monitor Plus shut down on December 17, 2025. Data broker removal protections ended on that date and all subscribers received prorated refunds for unused time, issued to their original payment method. The free Mozilla Monitor breach-alert service continues.
What is the best alternative to Mozilla Monitor Plus?
PrivacyOn is the best alternative. It covers 100+ data brokers with continuous re-scanning, includes 24/7 dark web monitoring at every tier, covers up to 5 family members on one plan, and costs from $8.33/month — less than the $13.99/month Monitor Plus charged. The initial scan is free, so you can see which listings came back after December 2025 before you pay.
Why did Mozilla drop Onerep?
Security journalist Brian Krebs reported that Onerep's CEO, Dimitri Shelest, had founded numerous people-search websites and retained ties to Nuwber, a data broker that sells background reports — a direct conflict with running a data removal service. Mozilla announced it would end the partnership and confirmed in November 2025 that it had.
Is Mozilla Monitor still free and worth using?
Yes. Free Mozilla Monitor still checks up to 20 email addresses against known breach data and alerts you to exposure. It just cannot remove anything. Use it alongside a removal service — PrivacyOn adds the removals plus its own 24/7 dark web monitoring from $8.33/month.
Did my data come back after Monitor Plus stopped?
Almost certainly. Data brokers resell records to each other constantly, so a listing removed once reappears when an upstream source repopulates it — often within weeks. Any removal that stopped in December 2025 has had months to reverse. A free PrivacyOn scan will show you exactly which brokers are publishing you now.
Do I get a refund for my Monitor Plus subscription?
Refunds were handled automatically. Mozilla issued prorated refunds for unused subscription time to the original payment method when Monitor Plus closed. If you never saw one, contact Mozilla support with your subscription details.
