Active Reader view
Firefox has an add-on called Active Reader View. It partially works on Tor. I can get the reader to come up and show two elements on the left hand side tool bar: Close, and Control (font), then it re-directs back to the original article in Pocket. I searched about this and saw a bunch of developer pages about this and that, but I was confused.
Is this supported? If so, how can I get my Tor browser to read (auditorily) to me?
