This page is part of the extension development documentation project.
Ask your questions in MozillaZine Forums. Also try browsing example code.
Note: development documentation is in process of being moved to Mozilla Development Center (MDC).
You can print information to JavaScript Console using the following method:
- Declare a variable (global if you're scripting your own window or your object's member if you're overlaying an existing window):
var gConsoleService = Components.classes['@mozilla.org/consoleservice;1'] .getService(Components.interfaces.nsIConsoleService);
(note, that you can use toJavaScriptConsole() function to open JavaScript console on startup)
- Define a function:
function myExt_logMessage(aMessage) { gConsoleService.logStringMessage('My extension: ' + aMessage); }
- Use it like here:
myExt_logMessage("Initialized.");
