Debug is not defined (FireFox 3.0.10)

Filed under: Uncategorized — noahblu @ 6:15 pm

I spent a long time today trying to track down an issue whereby all my Javascript code worked in IE but none worked on Firefox (that’s a first!!!).

I found I kept getting the following error in the FF Javascript console:

Debug is not defined

of course always followed by lots of other errors. I found I had to add an empty Debug function in javascript above the rest of my code:

function Debug(){}

Quite a hack, huh?

I’m using Script# ( to build much of my JS framework (I highly recommend) and it relies on this Debug object.




  1. Check out the sscompat.js file in your S# install. That defines a lot of those things that IE has out of the box when you’re running on other browsers.

    I haven’t tried it, but I think all you need to do is include the JS and the block at the bottom will do the work for you.

    • Sorry for the delay, but I _did_ try that and it worked great. Thanks a lot!
