Great add-on, glad that it supports e10s, but... Rated 3 out of 5 stars

The animations are slow when opening RSS. It slowly goes upward when I open an RSS article, it's so annoying because I accidentally press other feeds as the article opened is slowly going up, and very slow animation. If possible to remove the animation or optimize it for more speed?
Also, can we have a dark theme? It's the only thing keeping me wanting to go back to Bamboo Reader, dark for nights since the white is too bright.
