I have a Mac and Safari is my main browser but I also use Chrome alot. It had been years since I used Firefox but ever since I updated to the new Quantum browser I've been using it more and more. Mozilla touted the speed of this new browser and boy they weren't lying. The pages load really quick. It makes browsing much more efficient. Anyways I definitely recommend trying the new browser. I don't know if it's enough to get me to switch completely from Safari/Chrome but I definitely wouldn't rule it out
