I tried Android Nightly but there are still 2 small yet noticeable things Mozilla should improve (which are not at all linked to the page rendering in itself) - when it's done, it could really rival Chromium-based browsers:
- when you swipe fast, the page only scrolls by like 30%, instead of scrolling by 200% like in Chromium browsers. Basically it's impossible to quickly scroll a long page on Firefox (maybe it's configurable somehow in about:config?)
- when you long-press a link, it takes like 2-3 seconds for the menu to open. As I "open in new tab" by default, this quickly adds up.
