Pop-ups
Pop-ups
Opera will try to distinguish pop-ups that you have requested (typically log-in pages or similar) from pop-ups launched automatically from websites (typically advertising).
You can also choose to block all pop-ups, to open all pop-ups, and to open all pop-ups but only display them behind your other open tabs.
Set site-specific preferences
If you want to change pop-up settings for a particular website, you can use site preferences.
