you need to use the dev edition. this is fast... I found Electrolysis still quite slow. but the new engine ("Quantum"), is ridiculous fast. The last ~5 versions were such big improvements, that I even switched from Chrome. It's so good know that there is no need to keep Chrome. Firefox isn't good enough again, Firefox is the browser again.
