Arguably, having the menu visible is not the default setup, is it? The default fold-out "Firefox" menu simply doesn't have that issue and is not transparent.

I agree it's a problem in Thunderbird, which has a menu by default.

I think that if you try to tweak Firefox 4+ to look like 3.6 you're going to run into suboptimalities. It evolved. I think that if you get used to the changes, they're actually changes for the better (new menu giving more vertical room, tabs-on-top, etc).

If you tap the Alt key, the regular old menu comes up. It's transparent.
