A very basic whois extension, it just grabs the domainname from your navbar and does a whois on it in a new window.

Shows information about the current page (PageRank, Alexa rank, IP info, server response headers, whois and other SEO parameters)

Whois+ is an extension which allows you to do a whois, dns check, email verification and ping. When clicking the logo it will take the url out of the tab. If you don’t want that url you can change it.

After the url/email/ip is entered you can select what it should do. When you clicked the button it will open a new tab with the results.

In the options menu you can select from multiple sites where you can do the tests.
