can't execute javascript from URL window in Firefox 6.0.2

I used to be able to execute this simple line of java code from the URL window inside google maps to get the lat / long of a point.

javascript:alert(window.gApplication.getMap().getCenter());

however since I upgraded firefox recently, I get no result typing this into the URL window, not even an error message. I've checked all the javascript settings under tools, options, they're all enabled.

why does this no longer generate an alert window with the lat/long coordinates like it used to? What setting do I need to change to restore this functionality?

Chosen solution

On my version, I found under tools, Web Developer > Scratchpad - this popped open a window with instructions in there on how to run scripts.

(You can also try shift + F4 to open Scratchpad)

In firefox 6 javascript in the urlbar runs with a null security principal for security reasons. So it's mostly disabled. Users were installing malware. You can use the new scratchpad feature or you need a workaround. See cor-el in question 871828 for details.

Thanks guys for responding, I appreciate the replies. I was not aware this functionality had been removed in version 6. In any case, the scratch pad seems like a cool workaround
