Introduction
Vivaldi is a freeware Chromium based web browser developed by Vivaldi Technologies, a company founded by former Opera Software cofounder and CEO Jon Stephenson von Tetzchner. The browser is aimed at power users and previous Opera web browser users disgruntled by Opera's transition from the Presto layout engine to the Blink layout engine, which removed many popular features in the process. Vivaldi aims to revive the old, popular features of Opera 12 and introduce new, more innovative ones.
