Opera founder von Tetzchner: It's all gone to crap since I quit

"It's really sad, it's lost now," says Opera co-founder Jon von Tetzchner, reflecting on the fate of the company he left in 2011.

Opera had made serious inroads in the Noughties embedding a browser into consumer products, where it was a pioneer, and had a sizeable following on both desktop and mobile.

Its high performance Presto browser engine was one of the four left standing, alongside IE, Webkit and Mozilla. But it became neglected and Opera now wraps its own skin around the Webkit-based Chromium browser. It didn't have to be that way, said von Tetzchner, speaking to promote his new venture, a free consumer site called Vivaldi that touts privacy and security as it strong points.
