Console.log in firefox not working?

I am trying a simple console.log function in firefox

console.log("Hello World !");

you can try: http://jsfiddle.net/EkZjK/

You can also try the full code in a stand-alone HTML file:

 <html> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"> <script type="text/javascript"> console.log("Hello World !"); </script> </head> </html>

I get console logs in chrome.
But in firefox I do not see the logs.

I tried firebug console and CTRL + SHIFT + J
Both do not display a log message in firefox.

PS, I restarted FF, restarted Windows, tried on another computer and deleted the FF profile and created another one, reinstalled FF. But the problem still exists.

How to solve this?

Reinstalling the firebug plugin resolved the issue.
Now it appears in firebug console (not in CTRL + SHIFT + J )

I had the same problem with another reason - Hit CTRL - SHIFT - K to open a full console. The second line at the top has the NET, CSS, JS ... Logging tabs. Click the drop-down list next to logging and make sure that at least "log" is enabled.

  • Uninstall Firebug (or disable it)
  • press F12 and enjoy the console.

Firebug problem, it is no longer supported and may be unstable (see the official page). Other users here recommend updating it, but it may not work or work until the next Firefox update.
