Version 62 of Firefox will integrate a new add-on called Firefox Monitor that basically informs users if their email accounts have been compromised. The add-on uses the popular Have I Been Pwned database backend to check if the account has been compromised in data breaches.

Data breaches are a common occurrence in the digital world we live in and many users often find their accounts compromised when large data breaches occur. Firefox aims to provide a way for users to understand whether their accounts have been found in compromised databases or not by bundling the Firefox Monitor add-on in Firefox 62. 

Recently, Mozilla ran a Shield Study in the United States with about 250,000 users to gauge user experience and engagement with Firefox Monitor. Firefox Monitor relies on the backend created by renowned security expert Troy Hunt. The service is a database of all email accounts that have been compromised in data breaches. Mozilla says that users' email addresses entered into Firefox Monitor will be handled in an anonymized manner. 

So what's special about this add-on when you can directly visit from just about any browser? Well, apart from querying data from the backend, Firefox Monitor lets users sign up for alerts if their email address eventually appears in a newly compromised database. The add-on will also display a notification if the user visits any of the breached sites indexed by 

The initial rollout of the add-on will be restricted to about 0.5% of EN-US users on September 5 and will gradually rollout to 100% of EN-US users on September 25. If there are any issues with the rollout, the service will be made available only via the Firefox Monitor website. Those who wish to disable Firefox Monitor altogether can do so by going to about:config?filter=extensions.fxmonitor.enabled and setting the preference to False. Do note that this flag will only be available in Firefox 62 onwards; even the latest Nightly builds do not have this flag yet.

While maintains a highly comprehensive database, new entries with respect to latest breaches might still take time to get enlisted. Therefore, the usual advice of being careful online still applies.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
