It's Chrome for me. There was a period years ago though when i preferred Firefox, but that's only because the addon variety, now that Chrome is on the same level, if not above, Firefox lost that battle too. Quantum can be faster than previous FF versions, but when Chrome is still faster, what are we even talking about? Maybe if they can put together something, which is really faster than Chrome, they can win people back. Honestly it's too late for them to turn the trend (unless Google does something stupid to Chrome). More than half of the internet users use Chrome nowadays, which means less than 50% for all the other browsers. On desktop it's over 60%, on mobile it's under 60%, not because of FF, but because of Safari. lol
