How was I not aware of this? Slow clap for Moz though... they're going to get a LOT of browser data with this one. (I know they're getting mine)

I have been using it since 4 month. Its great. I love it. However the Domain authority it shows is not updated. For checking Domain authority of any website, I would rather recommend Ahrefs.com

You can use the MOZBAR browser extension.

Pros:

It gives you all the information about all the quality of the domain.

Cons:

You have to signup for the paid account for the detailed information.
