Yep, it's entirely possible the console opts in to let.

It also exposes some APIs that are not exposed in web pages by default 
and a few other interesting things like that...  Evaluating things in 
the console and in the currently loaded web page are _almost_ the same, 
but not quite.

In addition, in the particular screenshot you have there the currently 
loaded page is the Firefox start page, which is not exactly a normal web 
page either, so may have its own interesting things going on with both 
the script environment and its global.
