Date: 2007sep12 Keywords: debug, log Product: Firefox Warning: You don't usually do this anymore Q. How can I make Firefox output to a console? A. Start Firefox with:

<path-to-firefox> -console

Enter about:config in the address area. Right-click to make a new option. Like this:

browser.dom.window.dump.enabled = true

Restart Firefox Now your javaScript can do:

dump("Hello World\n");

So I don't have to add the newline I use a function like this:

function debug(a) { dump(a + '\n'); }
