Viewing dump() output

You can use dump() statements instead of alert() to display debug information for your extension. In order to view the dump() output, go to about:config, add new boolean pref browser.dom.window.dump.enabled and set its value to true.

Then start Mozilla (or Firefox or Thunderbird) with -console parameter (more information). You will now be able to see dump() output in the opened console window.
