Chromium based browsers such as Vivaldi support the concept of user profiles. These are different user configurations, under a single operating system login. You could use different users profiles for home and work, or to allow a friend to use your browser without messing up your setup or interacting with your open tabs.
Vivaldi does not currently provide any user interface for switching user profiles outside of the command line switch
—profile-directory= (where you pass the name of the profile). However on macOS, you can make a quick launcher application in Automator.

This Automator folder action will monitor the Downloads folder for new dmg files and automatically unpack them into a similarly named sub directory. It requires no interaction from the user. On completion a notification will display.
As mounting and extraction happens in the background you save time, since you can continue to work. In addition with all disk image contents pre-copied to disk, moving any .app to "/Applications" is pretty much instant (or in the case of Vivaldi, you could run it in standalone mode directly from the created extraction folder).

The following allows macOS users to run two different Vivaldi's alongside each other (e.g. stable and snapshot), with their prefences/settings stored seperately. This is also handy if you want to do an initial test of a snapshot in a self contained manor, without touching your main prefences/settings.
It works by causing launch Vivaldi in such a way that it stores its prefences/settings in a directory next it (called "Vivaldi Data"), rather than using the default prefences/settings directory ("~/Library/Application Support/Vivaldi").
