selenium - reading the firebug console in javascript

Question

I'm looking for a way to read the most recent command that was logged to the firebug console.

For example, I could have something that does

console.debug('The most current request URI is /sweatsocks');

And then another piece of (pseudo)code could then

if (mostRecentConsoleEntry().endsWith('/sweatsocks')) {
  // do some stuff
}

The context being the debug statement would be in the code under test, and the console checking would be done inside a selenium script. This would let me observe information buried deep in js functions as well as stuff that is built at runtime.

You could overwrite the console.log function to add whatever extra functionality you need.

var oldLog = console.log;
var lastLog;
console.log = function () {
    // do whatever you need to do here: store the logs into a different variable, etc
    // eg:
    lastLog = arguments;

    // then call the regular log command
    oldLog.apply(console, arguments);
};

This won't be the most bulletproof solution, since console allows printf style syntax:

console.log("%d + %d = %s", 1, 3, "four");

...but it's probably a start for you.
