The browser is somewhat similar to Google Chrome, but it offers better privacy and security features, so if you’re in need of a new browser, Opera is the way to go.

Among the greatest Opera features, you will also find a built-in adblocker, free, unlimited VPN, integrated messenger, workspaces, and a video pop-out function. And that’s the tip of the iceberg, really.
