Install Vivaldi 1.7 (stable) on Ubuntu / Linux Mint

Vivaldi is a feature-rich, next-generation web browser application based on the powerful and open source Chromium project, from which the popular Google Chrome web browser is derived. The application is freely distributed and cross-platform, created by the former CEO of Opera Software, built using modern Web technologies like React, JavaScript, Node.js, and Browserify.

A web browser designed for you

The main goal of the Vivaldi project is to make a highly flexible, low on resources and extremely fast web browser software that works across all mainstream computer operating systems, a web browser that is rich in functionality and designed for you, the user.
