Rated 5 out of 5 stars

After google lost it's real-time, this came in handy. I don't use the search bar, just the address bar, so I made heapr the keyword URL:about:config, find "keyword.URL", and make the string value:http://www.heapr.com/#l=web&q=Just like old times :)

(I just use the link in my bookmarks bar, not this add-on, anymore. And Duck Duck Go, but Heapr can be great!)
