Vivaldi is a new web browser from Jon von Tetzchner, former CEO of Opera. It’s built on the Chromium rendering engine and is targeted at power users, with Quick Commands, Speed Dials, and Tab Stacks being a few of its landmark features.

I’ve spent a little while using it and it feels remarkably stable for a technical preview. I can’t say I’m a fan of the browser’s design, though — I don’t like that portions of the interface change colors based on the web page you’re viewing, but to each their own.

I’m not optimistic that Vivaldi will last, simply because the market is so much more mature than it was a decade ago. Don’t get me wrong, I’d love to see a larger variety of successful web browsers, but I don’t see any evidence that people are willing to switch to a new one without the help of a multi-billion dollar company promoting it.
