var properties = {
disabled: false,
title: "My Extension",
icon: "icon.18x18.png"
};
// Add the button to the browser UI
var button = opera.contexts.toolbar.createItem(properties);
opera.contexts.toolbar.addItem(button);
// Update the button title each time the button is clicked
var i = 1;
button.addEventListener('click', handleClick, false);
function handleClick() {
button.title = "You've clicked the button " + i + " time(s)";
i++;
}
