About 100 million Yahoo Mail users account is hacked in August 2013. In the next year, more than 500 million users were lost. The acclaimed Apple's Icloud is also in the possession of hackers for user information security. Unread information includes e-mail addresses, passwords and more information. There are specific information in this billions of user information, so long it was not known. But now if any user data is stolen, then Mozilla Firefox browser will tell. The company is going to add a new feature called Firefox Monitor soon.

In the event of theft of Internet data, Firefox browser users will know what information they have been stolen, whether they have been stolen or not. There is a website named 'How I Bin Pond'. The website provides free services to find such information. Troy Hunt, the creator of Howe Iin Pond, will give Firefox to their service. He said that the service has been running for a long time, but its database is not very rich. And so he will pay for the users of the Firefox browser. The users will provide the necessary information on the new Firefox Monitor website. The user can verify if any of his information is a victim of digital theft. Troy is hopeful that more customers will be benefitted through new services.

Firefox continues to work experimentally with the facility. About 250,000 users will be invited to use the new facility this month, said Mozilla authorities. And those who do not use Firefox, they have access to the hasibeenpwned.com address website and know whether the information was stolen or not.
