The Chrome extension is available to Insider subscribers. 

You can download the Chrome extension from the Chrome Store here.

After downloading the extension there are two ways to navigate the extension.

Simply navigate to any webpage, highlight an address on the page, right click and select r+ from the drop down. The dashboard will prompt you to login before loading your address. 

Once you have your dashboard opened, you can click on the "reset address" button. This will prompt the search bar. You can enter your desired address and view the data without having to highlight any addresses.
