Mozilla has partnered with Australian security researcher Troy Hunt to create a user-friendly service where users can check whether or not their passwords and email addresses have been exposed in data breaches. Mozilla’s new tool, called Firefox Monitor, accesses to Hunt’s Have I Been Pwned database of billions of emails exposed in data breaches.

The free Firefox Monitor service functions much like Hunt’s Have I Been Pwned. You can search for your email address in the service’s search box, and if the address and its password have been part of a data breach, you’ll be shown when that breach happened and which service, specifically, was compromised.
The tool can also proactively alert you if your email address is part of a new data breach. This should give you time to change your passwords for exposed accounts quickly.
Hunt’s Have I Been Pwned database often includes compromised email addresses from new data breaches that haven’t yet been made public. Security researchers sometimes tell him if they've found evidence of a new data breach, or if they've seen stolen credentials sold on underground markets. The Firefox Monitor gives Hunt's database a wider audience wider than he can reach with Have I Been Pwned alone.
Firefox Monitor might even be able to tell you about a breach even when a company keeps the breach secret. Some companies keep quiet for weeks or months until they have figured out what happened. (If a breach affects customers in Europe, however, new GDPR rules mandate notification within 48 hours.)
