Switching to Vivaldi and modernizing bookmarks over speed dials of home screen with some logos from the web, that works for me. I have run Firefox, Chrome, Edge, Vivaldi and Opera. I use Vivaldi on Ubuntu and with Chrome based browser you get about 2x speed in math but that’s not always necessary for page loading to be any faster. This days skins should not slowdown any browser but you never know. Basic functions are more or less the same in all browsers. Firefox can do large block of text like my Lots of text HTML5 demo but the rest of the browsers has 2x math speed compared to Firefox, so every browser is good for something or for someone. Firefox needs to advance JS speed and get some proper speed dial of home screen with better configuration and that’s about it what like to see in this browser in the future. Link
