<sub>this.quot = function(evt) {
if(evt.shiftKey) {
this.showPopup(this);
return;
}

var link="https://www.google.com/accounts/ServiceLogin?service=cl&passive=true&nui=1&continue=http://www.google.com/calendar/render?hl=en&tab=wc&followup=http://www.google.com/calendar/render?hl=en&tab=wc";
var label="Google Calendar";
var head =(document.getElementById('sidebar-title').getAttribute('value') == label);

switch(evt.button) {

case 0:
gBrowser.selectedTab = gBrowser.addTab(link);
break;

case 1:
gBrowser.addTab(link);
break;

case 2:

if (!head) {
openWebPanel();
var sbLoc = document.getElementById('sidebar').contentDocument.location;
sbLoc.href = link;
document.getElementById('sidebar-box').hidden = false;
document.getElementById('sidebar-title').value = label;
document.getElementById('sidebar-box').collapsed = false;
document.getElementById('sidebar-splitter').hidden = false;
return;
}

if (head) {
toggleSidebar();
}

break;

}
}
this.showPopup = function(node) {
var popup = document.getElementById('custombuttons-contextpopup');
var x = node.boxObject.x;
var y = node.boxObject.y + node.boxObject.height;
document.popupNode = node;
popup.showPopup(node, x, y, 'popup', null, null);
}

this.setAttribute('onclick', 'this.quot(event);');
