Aero Firefox 🦊

Warning

The latest release no longer works on Firefox 141 and over. If you want to use the theme on newer versions, download it from the 3.0-test branch.

Brings the Aero titlebar buttons from Windows Vista/7 to modern versions of Firefox, complete with hover and active effects!

This theme uses images extracted from the official Windows 7 msstyles theme file, so the buttons are as accurate as possible (besides the hover glow).
