UPDATE: I no longer recommend Firefox. Mozilla used to be for a free and open web. Now they support censorship. So now I recommend Brave to my friends and family.
Data breaches seem like they are in the news weekly nowadays. It happens so much it is easy to overlook or miss a data breach that may involve you. But Mozilla has come out with a new tool called Firefox Monitor that may help with that.
Has your account info been stolen?

Firefox monitor partnered with have
It looks like it basically does the same thing as the “have I been pwnd” page. But with the backing of Mozilla, I think more people are likely to trust it. I for one do not put my e-mail address into services I do not know.
Having the Mozilla name behind it also boot awareness. Out of the 3.1 billion e-mail addresses in the database only around 2 million e-mails are being watched by users. Troy Hunt the creator of the database said in a blog post “clearly, I’m barely scratching the surface. However, that scope is about to expand dramatically via 2 new partnerships which I’m announcing today, starting with Firefox”
How Firefox monitor works
You can simply just search for your e-mail address but the thing I think they are pushing is the subscription service. This way you can get notifications anytime your addresses appear in a new data breach.
To check it out just head on over to the Firefox Monitor page, put in your e-mail address, and give it a test drive! Then if you want you can sign up to have your addresses monitored automatically.
