If it weren’t for the fact that I’m a bona fide Netscape Mozilla fanboy, I’d be all over the Vivaldi browser now. It’s fast, snappy, developer-friendly, cross platform, and has some smart features. When you’ve used the browser for just a day, you’ll totally understand the positive reviews of Vivaldi.
But for now, I’m sticking with the open source Firefox. However, Vivaldi has made Chromium my third choice browser (for now).
