Excellent add-on, needs one option and FF 5 Rated 4 out of 5 stars
Very good add-on, reasonable features, intuitive to use. Worthy of supporting and contributing to author.
ONE MAIN FEATURE REQUEST: PLEASE allow user to optionally select slightly larger readout font size. MUCH needed for far easier readability
ONE MAIN WORRY: Does NOT work with the new Firefox 5, yet. Pray that author can remedy that situation.
