I installed Opera recently and Opera asked me if I want to activate a dark theme.
I said yes, but I really don't like it.
The problem is, I don't find an option to deactivate it.
Can anyone help me?
Go to menu > settings > browser > user interface and uncheck the "enable dark theme" or, on the speed dial page, click the 3-lines button on the top right corner and again uncheck "enable dark theme".
