Firefox Extension Developement how to debug preferences page?

Question

How do I debug, like console.log(); the Preferences Page of the Extension? Thanks

Answer 1

您应该能够使用Firebug.Console.log()使用Firebug进行调试。

Answer 2

I would just use window.dump . If you really want the Firebug console, you could probably get a reference to main browser window using:

var mainWindow = window.QueryInterface(Components.interfaces.nsIInterfaceRequestor)
               .getInterface(Components.interfaces.nsIWebNavigation)
               .QueryInterface(Components.interfaces.nsIDocShellTreeItem)
               .rootTreeItem
               .QueryInterface(Components.interfaces.nsIInterfaceRequestor)
               .getInterface(Components.interfaces.nsIDOMWindow); 

( from here ) and then call mainWindow.console.log . Haven't tried it, but I think it should work.
