Firefox Monitor shows if your personal information was lost in a hack

The idea behind launching Firefox Monitor is to let users know about data compromises in a timely fashion, giving them a chance to change passwords and safeguard personal information from potential threats. The tool was launched after an extensive testing and is supposed to help users after a data breach.

With more and more databases containing stolen user credentials, from email addresses to credit card numbers, now being illegally hosted on the internet, monitoring services like Mozilla's one make a lot of sense.

Back in June this year, Mozilla and Have I Been Pwned (HIBP) creator Troy Hunt announced that they were teaming up to integrate the very large HIBP database into Firefox.

In addition to Firefox Monitor, Mozilla also recently announced a new anti-tracking initiative that aims to help block the unrestrained data collection activities online.

Accessible via, you can type in your email address to see if it's been involved a publicly known past data breach.

Firefox Monitor also gives you the option to sign up to be notified of any future breaches involving your email addresses.

Mozilla has promised to launch a swathe of security and privacy tools throughout this fall. Monitor consists of an input form - with Firefox download links - submits hashed email addresses to HIBP and performs a bit of processing on the returned data.

Speaking about Firefox Monitor, Hunt swooned: "This is major because Firefox has an install base of hundreds of millions of people which significantly expands the audience that can be reached once this feature rolls out to the mainstream".
