Make Firefox Awesome Bar Drop-Down Menu Slightly Transparent

[(Account no longer active)]

Is there a way to make the Awesome Bar drop-down menu slightly transparent? A slight blur would also look nice (reminiscent of IE 5 on Mac back in the day).

I keep forgetting they call that the "awesome bar." So not... awesome. 

 

I'm sure you could do it with a GreaseMonkey script, though I would have no idea how to code that.

Edit the userChrome.css file in your profile's chrome directory (%appdata%\Mozilla\Firefox\Profiles\________\chrome) and add:

#PopupAutoCompleteRichResult[type="autocomplete-richlistbox"]
{
    opacity: 0.8 !important;
}

Change that opacity number to whatever.  If the file doesn't exist, make one.  The image below is 0.5.. a tad much but you get the idea as an example.

Not that I was looking to do this to my FF, but nice piece of information anyway. Thanks.

Thanks for your suggestions. Is it possible to add a blur effect too?
