This browser came to me as I have been a longtime opera user; in most cases you have an updated Opera; the developers are from the "old Opera" before it went to other hands. Installation is simple, and straight forward; you are asked as how you wish the browser to be set up; tab placement, color, and other setup options. As soon as this is done open the preferences, and set it up to your liking. You have a zoom function, and it uses Chrome extensions, like opera, but without the extension to install chrome extensions; Vivaldi has that built in. It is "rock solid" since I use my computer very conservatively, may be the reason, on my end. An interesting fact; opera "crashed" when I installed certain extensions; Vivaldi did not. As I have Cerebral palsy, Vivaldi, has the same accessability features as the version 12-16 of the old Opera. It does not have a built in VPN; those who have a requirement for that will find many VPS on the Chrome Store. I gave this browser a 5 because it meets the needs of the disabled; I also am a member of the Vivaldi community as I was the "old opera"
