Brucehankins As a former Opera user of many many years: Vivaldi is the one true Opera.
Opera today is a shadow of its former self. It used to be my browser, my email client, my calendar, and my IRC client. There was nothing like it. It used to be my development browser of choice because anything I implemented that worked on Opera was guaranteed to work on every other browser. They followed W3C specifications to the letter and never implemented a feature until it had a formal specification. No draft features. No half-baked implementations of HTTP/2.
Now it's just Chromium with a different interface and the odd useful feature that they brought back from the old Opera.
