Bleeping Computer: “Vivaldi 5.6 was released today with a Mastodon client integrated directly into the browser’s sidebar, seamlessly incorporating the rising social media platform in the browser’s interface. Vivaldi is a cross-platform web browser created by the former co-founder and CEO of Opera Software, Jon Stephenson von Tetzchner. It is geared towards power users who want multiple customization options that enable them to create a highly tailored user experience on their browsers. Moreover, the browser features a rich set of in-built tools that respect user privacy, like an email client, translator, calendar, contacts manager, mobile sync, and a screen capturing tool. Vivaldi has been a vocal supporter of distributed social networks based on open standards, and in November, it became the first web browser project to create an instance on Mastodon’s fediverse. The release of Vivaldi version 5.6 integrates Vivaldi’s own Mastodon instance, ‘Vivaldi Social,’ directly into the browser’s sidebar. Vivaldi’s Mastodon instance counts over 11,000 active users and is integrated directly into the federated social platform, allowing users to interact with anyone on other instances. Vivaldi Social will now be easily accessible via the Panel. Users can also add it permanently onto the sidebar, keeping it in view in a split-screen-styled browser window..”
