I’ve been working together with Richard Marti of late on bug 569400 to implement Aero glass for the Windows version of Thunderbird, similar to what the Firefox devs are doing for their 4.0 release. This makes things look a lot sweeter, and blend in better with Windows 7.
Since there are several parts and widgets getting touched and that it therefore needs a lot of testing and feedback before we unleash it to the majority of our users, we decided to implement it as a theme before doing any patches for core.
Here is where I need your help. If you’re a Thunderbird user on Windows, download the xpi and take it for a test spin. You’ll need version 3.2 of Thunderbird on order for things to work correctly. Get a nightly build here.
Leave feedback here or on the bug!
