Log to Firefox Error Console from JavaScript

Question

Is it possible to add messages to the built-in error console of Firefox from JavaScript code running in web pages?

I know that I there's Firebug, which provides a console object and its own error console, but I was looking for a quick fix earlier on and couldn't find anything.

I guess it might not be possible at all, to prevent malicious web pages from spamming the log?

If you define a global function that checks for the existence of window.console, you can use Firebug for tracing and still plays nice with other browsers and/or if you turn Firebug's console tracing off:

debug = function (log_txt) {     if (typeof window.console != 'undefined') {         console.log(log_txt);     } }  debug("foo!");
