An event is initiated when the application starts up and when the profile is changed. For more information please look at the following link: [http://lxr.mozilla.org/mozilla/source/toolkit/mozapps/extensions/src/nsExtensionManager.js.in#2703 nsExtensionManager.js]

If you have a similar code base as the following:
:<pre>
:onBookmarkContextMenu: function(event, id) {
: document.getElementById("bookmarkPopup").showPopup(document.getElementById(id),
: event.screenX + 6, event.screenY + 6, "popup", "bottomright",
: "bottomright");
:
:}
:</pre>
Use the hidePopup() function to solve this issue.

An example of this is this:
:<pre>
:// Associate the progress listener for a "browser" to a listener object
:
:browserObject.addProgressListener( listObj,
: Components.interfaces.nsIWebProgress.NOTIFY_STATE_WINDOW );
:
:// Remember to define the object, something like this:
:
:listObj = new Object();
:
:listObj.wpl = Components.interfaces.nsIWebProgressListener;
:
:listObj.QueryInterface = function(aIID) {
: if (aIID.equals(listObj.wpl) ||
: aIID.equals(Components.interfaces.nsISupportsWeakReference) ||
: aIID.equals(Components.interfaces.nsISupports)) return this;
: throw Components.results.NS_NOINTERFACE;
:
:}
:
:listObj.onStateChange = function(aProgress, aRequest, aFlag, aStatus) {
: if (aFlag & listObj.wpl.STATE_START) {
: // This fires when the load event is initiated
: } else {
: if (aFlag & listObj.wpl.STATE_STOP) {
: if ( aFlag & listObj.wpl.STATE_IS_WINDOW ) {
: // This fires when ALL load finish
: }
: if ( aFlag & listObj.wpl.STATE_IS_NETWORK ) {
: // Fires when ALL load are REALLY over,
: // do something "final" here
: // (my two cents)
: } else {
: // This fires when a load finishes
: }
: }
: }
: return 0;
:
:}
:
:// This fires when the location bar changes i.e load event is confirmed
:// or when the user switches tabs
:listObj.onLocationChange = function(aProgress, aRequest, aURI) {
:
:// do whatever you want to do
:return 0;
:
:}
:
:// For definitions of the remaining functions see XulPlanet.com
:listObj.onProgressChange = function() { return 0 };
:listObj.onStatusChange = function() { return 0 };
:listObj.onSecurityChange = function() { return 0 };
:listObj.onLinkIconAvailable = function() { return 0 };
