The do-it-all browser? on June 9, 2021, 8:51 Why it matters: Chrome might dominate the browser market, but there are plenty of compelling alternatives available. One of these is Vivaldi, which has just received several interesting new features in its latest 4.0 release, including a built-in email client, RSS feed reader, and calendar. Years after the developers promised it would come to the browser, the Mail beta has arrived in Vivaldi 4.0, offering a more private option than web apps made by "Big Tech" companies, apparently. Pretty much any email provider that supports IMAP and POP protocols will work with Vivaldi's client, and there's built-in support for Gmail. You can also search a local database of retained messages when you're offline.
