Wow, I am amazed at the speed of this amazing browser - Firefox Quantum.
Firefox Quantum has a concept of loading the CSS engine and other changes which makes the browser a breeze to use with.
Firefox Quantum is releasing in November 2017. But why wait - Go ahead and try this browser out here - https://www.mozilla.org/en-US/firefox/channel/desktop/#beta
And for all languages the website links is here - https://www.mozilla.org/en-US/firefox/beta/all/
You will certainly consider leaving Google Chrome after trying the browser out!!!!
