Thanks for updating this excellent extension. It is so useful that I used it error and all. Now it is clean on Firefox 20 I kind of miss the interaction with the error pop up [joke!]. Easy to install and once configured to your taste the preferences carry over to new editions flawlessly. For new users you *do* have to configure it and it takes time to do so.
