WHOIS lookup add-on for Firefox

Do you often need (or simple want) to know the owner of a certain domain name? Are you professionally involved in domaining or web hosting? Is Firefox your favorite browser? Then look no further, because you've found the ideal solution. Our lightweight add-on will allow you to perform multiple WHOIS lookups with a single click, without bogging down your browser.

How it works

Vitzo WHOIS Lookup adds a small unobtrusive button in your address bar which, when clicked, looks up the WHOIS information of the domain that's present in the URL bar.

Another option, when you need to lookup domains which are contained in text on a certain page, is to perform WHOIS queries using the context menu. Simply select and right click the text which contains the domains. Our tool will open the results in new tabs, ignoring any text that isn't part of any domain name.

The results are the same as if you'd use our WHOIS tool directly. All major and most of the smaller TLD's should be supported. If any of them don't work, feel free to let us know.

How to get it

Installing this Firefox add-on is extremely easy; 

1. Visit the WHOIS lookup add-on at Firefox's website.
2. Click the "Add to Firefox" button and then confirm the prompt.
3. Restart Firefox

You should now see the add-on listed when you click "Extra" -> "Add-ons" as such:
