Can’t you change the user profile in the command line with a flag? Surprised it takes this long to implement that in a gui fashion.

The most important part of profiles is being able to right-click on a link and open it in a different profile. I don't see that mentioned. I typically have multiple profiles open at once.

Edge has the best implementation where you can define sites opening in certain profiles. Pity ms ruined that browser - it is completely untrustworthy with it auto turning on options such as syncing.
