Firefox 4 nightlies get Aero Glass

As part of the deep theme updates planned for Firefox 4, the nightly development releases now feature Aero Glass on Windows Vista and 7.

The feature was available first in early April but pulled back soon after to iron some important bugs.

The screenshot above also shows the tab bar above the location bar, an optional layout in Firefox 4, and the menu bar optionally hidden, a feature introduced in Firefox 3.6 for Windows platforms.

So far, Aero Glass does not affect personas which are displayed opaque just as in Firefox 3.6.
