GM_log and other GM functions do not work in Greasemonkey scripts

Question

I created a "Hello World" Greasemonkey script in Firefox that contains only one line of code:

GM_log("Hello World");

This did not seem to function, at least it did not produce any results in my firebug console.
Same thing with other GM _... features like GM_wait

When I replaced:

GM_log("Hello World");

with:

alert("Hello World")

it worked (so the script headers are not a problem).

I also set the following options about:configto true:

Are there any other settings for changing GM _... functions to work in Greasemonkey scripts?

Do I need to change other firebug parameters for GM_log messages to display in the firebug console?
