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.
- Open the
Automator.app(part of macOS) and create a new “Application”
- Drag “Ask for Text” (found under “Text”) into the actions area
- Set the “Question” to “Vivaldi Profile Name?”
