Error with find _firebugConsole

[cobra90nj]

Hi, why when I open a new tab in firefox, and open firebug for testing
my js code (aloso a simple alert("hello");) it returns "Firebug cannot
find _firebugConsole element true Window about:blank" ?
Firefox 3.5.5
Firebug 1.4.5

Thanks for your support.

The firebug console is not injected into about:blank or any other page
that does not have Javascript.

Eventually we hope to replace the current console and command line
implementation to avoid these restrictions.
