An amazing addon that works in Firefox Android as well that I have been waiting for a long time. The one thing that I've noticed that can and should be improved is if the side screen scroll highlight worked and behaved similar to the in browser highlight of Firefox app as the side screen highlight of the addon are longer and tend to block the words on that part of the screen and also clump together if there are many highlights on a page instead of being spread out. Otherwise an amazing addon that I think every Firefox user should have irrespective of the platform.
