Opera buttons is a sort of extension that has existing in Opera for a long time. They are an easy way to customize Opera’s toolbars to make your favourite features more accessible.
Here is a quick example showing you how to add a new private browsing button:
- Drag the link “Private window” and drop it just to the right of the closed tabs button
One click on that new button, and you have got yourself a private window to … surf around in.
