Very good, does its job very well. I have used it now for a long time and I am very happy. Just a small dissatisfaction concerning the google webpage lately: Since a few weeks or so, the google warning is loaded for a few seconds, then it vanishes. Could this be due to a technical change on the google webpage ... ? Apart from this minor issue, my experience with the add-on is very good. Browsing on the web feels *much* more convenient.
