# Mozilla Monitor review (2026): is it any good? > Free data breach scanner with alerts and guided fix steps Checked Nov 12, 2026 ยท graded Nov 12, 2026 by ToolGPA. 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. - **Category:** Data Removal Services - **Made by:** Mozilla - **Website:** https://monitor.mozilla.org - **Runs on:** Web - **Who should skip it:** Skip it if you want your details removed from people-search sites, as it doesn't do that. - **Facts last checked:** Nov 12, 2026 ## Pricing As of Nov 12, 2026, Mozilla Monitor is free to use. - **Pricing model:** Free - **Free plan:** Free breach scan and alerts for up to 5 email addresses, with guided steps to resolve each exposure. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Free | $0 | Breach scan, new-breach alerts and guided fix steps for up to 5 email addresses. | Read from https://monitor.mozilla.org/en/how-it-works on Nov 12, 2026. Prices change, so confirm with Mozilla Monitor before buying. ## Key features - **Breach scan:** Searches known data breaches using just an email address. - **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. - **Alerts for new breaches:** Checks each newly detected breach against your address and emails you if you are in it. - **Five email addresses:** All subscribers can monitor 5 email addresses at no cost. - **Breach database:** A public list of reported breaches since 2007, showing the date each was added and which data types it exposed. ## 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. ## ToolGPA grades **GPA: 2.8 out of 4**, graded Nov 12, 2026. 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 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.
