Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 10 of the 11 other data removal services we grade
Mozilla Monitor searches known data breaches for an email address, walks the user through resolving each exposure, and sends an alert when a new breach includes that address. The pages we read describe breach monitoring only and list no paid plan and no removal from data broker sites.
To get you started, here are 8 things to know about Mozilla Monitor, taken from its own pages and our grades.
No store rating on record, but you enter an email address and get a result, with nothing to set up.
- 1
Best for checking whether your email is in a breach
Mozilla Monitor searches known data breaches for an email address, sends an alert when a new one includes it, and walks you through the fixes.
- 2
It is free
Mozilla Monitor has no paid plan at all. Free breach scan and alerts for up to 5 email addresses, with guided steps to resolve each exposure.
- 3
It runs on Web
Web.
- 4
Breach scan
Searches known data breaches using just an email address.
- 5
Guided resolution steps
Because fixing a breach usually means manual steps such as changing passwords or placing a fraud alert, it gives instructions instead of fixing exposures itself.
- 6
Alerts for new breaches
Checks each newly detected breach against your address and emails you if you are in it.
- 7
A 2.8 GPA, above 10 of 11
That is against the other data removal services we grade, on value, the free plan, features, ease of use and platforms.

The report card
Best for checking whether your email is in a breach
Mozilla Monitor searches known data breaches for an email address, sends an alert when a new one includes it, and walks you through the fixes. It is free for up to 5 addresses, but it does not remove anything from data brokers, and the fixes are yours to carry out.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Free outright for up to 5 email addresses, with no paid plan shown on the pages we read. |
| Free plan and trial | A | A free breach scan and alerts for up to 5 email addresses, with no cap an ordinary person would reach. |
| Features | D | One narrow job: breach scan, alerts and guided steps. It doesn't remove personal information from people-search sites or data brokers. |
| Ease of use | B | No store rating on record, but you enter an email address and get a result, with nothing to set up. |
| Platforms and integrations | C | Web only, by email address, and the listing names no integrations or apps. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Mozilla Monitor is for
- Fits if you only want to know whether your email turned up in a breach
- Works for a family checking up to 5 addresses
Who it is not for
- Skip it if you want your details removed from people-search sites, as it doesn't do that
- Not for you if you want it to fix breaches, because the steps are yours to carry out
- Watch out: it monitors email addresses only, not phone numbers
- Watch out: Mozilla's help pages blocked our fetch, so we couldn't confirm whether a paid plan still exists
Good to know
Good for
- Anyone who wants a free check of whether an email address appears in known breaches
- People who want plain next steps after a breach, such as which passwords to change
- Households watching several email addresses without paying
Worth knowing
- It checks breaches and does not remove personal information from people-search sites or data brokers; the pages we read mention no such service.
- It cannot resolve breaches for you: the steps, such as changing passwords, are yours to carry out.
- Monitoring is by email address; the pages we read do not list phone numbers or other identifiers.
- Mozilla's help pages blocked our fetch, so we could not confirm whether any paid Monitor plan still exists.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
Mozilla Monitor is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 10 of the 11 other data removal services we grade.
What you could make
- Reports: an app builder makes this well.
What you could not
- Opt-out requests to hundreds of data brokers, sent again whenever they list you again.
What this rests on. Mozilla Monitor’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
