Rated 5 out of 5 stars

It works good, is useful and I have the following suggestion:
Highlighting the active input-element is done outline and changes height of the element. This leads to the unpleasant effect, that height of the site always slightly changes by some pixels, if element is focused.
It would be good if there was used another method to highlight, which does not have this unwanted effect.

This review is for a previous version of the add-on (1.3).
