Over the weekend I built a #speed-reading web #extension for #Firefox called "Stutter". It will soon expand to cross-browser and mobile support.

Try it out and let me know how it works for you. If you have any suggestions, you can log them on the github page here:

You can see planned next steps on my todo list on the README
(please boost so I can gather feedback)
