I love the idea of this tool and how responsive the developer has been to respond to earlier suggestions, i.e. add facebook, open in new tab, etc.
I'm having trouble getting it to work for me.
First, I'm having a problem - when I highlight the name, open the tool and click on the site I want to check, I always get "not found" because what was searched was [object Object]. Is that a bug or setting in my browser?
Second, I too would prefer being able to search all sites at once...I'm not apt to use it much if I have to manually check each site - just as easy to google it!
