MXtoolbox lookup tool

A simple and small extension to check all kind of records on MXtoolbox.
I created this because I need to check A and MX records often and this saves me time.

Usage:
Default the extension starts with a: (A record), just fill in the domain name and hit go.
To check other kinds of information, like MX records or whois information, just type mx: or whois: instead of a:
It's also possible to check MX and A records directly from the context menu.
