Rated 3 out of 5 stars

Works well, but there is a problem. The more one uses it within a browsing session, the less and less text you can select until you can only select a single sentence and have it work. Somehow it's not letting go of it's memory after it stops speaking. If you restart the browser I think it starts working again.

This review is for a previous version of the add-on (0.5).
