Hunter for Firefox

If you want to find email addresses from a specific domain, then you're not at all short on luck. You could employ the services provided by one of many email extractors (or email spiders, as they're also called) out there, you could turn to various specialized WhoIs-like online services, or you could use Hunter.

Hunter is a nifty, cross-browser extension available for Chrome and Firefox that makes it effortless for you to find email addresses of a website you are currently visiting without having to leave your browser's main window.

And that's not all Hunter can do: it also allows you to locate emails based on names and job titles, as well as verify the validity of those emails. It's also worth pointing out that Hunter displays the public sources from where the results have been collected.

Even though we're going to focus more on the Firefox version of the extensions, please note that both it and the Chrome iteration are almost perfectly similar regarding functionality.

That said, once installed, you can find emails related to various domains by simply visiting a website and by clicking the toolbar icon. You are provided with a list of all email addresses and the total number of sources.

From this point onwards, you can either verify the emails, inspect the sources one by one, add them to your list of leads, or perform an even more advanced search by entering the contact's first and last name, directly within the extension's compact UI. If you need to download the whole email list, please note that you can get export it in CSV form, but only from the Hunter web client.

As a conclusion, Hunter for Firefox is a very efficient and useful extension that offers a convenient way of extracting email addresses of various domains directly within the Mozilla-vetted browser's toolbar.
