@Lab_gas_flow Opera doesn't have Chrome's built-in profile switcher. The Cleanest way is creating a shortcut with a custom directory flag: --user-data-dir="C:\OperaProfile2", or using the built-in Workspaces feature if you only need separated tabs and contexts.

@jewellok how can I change the Opera profile mean a separate profile of each user just like Chrome offers.

are you talking about Pop-up Ads or some other functions as opera blocked Pop-up ads....
