I have been using Sage for years and I thought I was all set with it until I was forced to look elsewhere because of FF 57. You my new friend out did yourself. FANTASTIC reader. Every inch of it is polished and trim. It was like going from a bike to a Lexus. What a great reader. I am so glad I found it and hope you work on some other projects for this new Firefox. Would be a shame not to. Thank you for this work.
