Image from store MXtoolbox lookup tool
Description from store 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. Changelog: Version 1.4: - Added options to context menu in Chrome. Right now only for A and MX record (assuming those are most frequently used). Version 1.3: - On request added focus on input field when opening popup Version 1.2: - Solved problems with JS files, not loaded due to security settings. - fixed icons (added more sizes). Version 1.1.2: - Renamed icon. Version 1.1.1: - Issue with manifest file, unable to update or install extension. Version 1.1: - Ability to choose record from select list - Select MX, A, TXT, SPF, SMTP, WHOIS, Blacklist. - Submit with enter key to save time Version 1.0: release

    Any chance you could have box autofill the website open in the current open tab? Then we would hit Go to search it. 95% of the time I use this extension, it's to check the page I'm currently looking at. I love the extension and appreciate your work!
