Glad to see Noia back, but there are some bugs with the title bar when you hide the Menu Bar on Windows XP. Windows Vista/7 options try running on Windows XP instead of being ignored.
All you need is a custom Firefox app button on Windows XP and nothing else.
I don't know whats wrong with your FF but here is anything fine on WinXP. Look at the pic.
You have to set the titlebaroption from Aero Basic when you hide the menubar on XP.
"Windows Vista/7 options try running on Windows XP instead of being ignored"-> I don't understand what you mean by that.
"All you need is a custom Firefox app button on Windows XP and nothing else."-> I could add some color to the FF appbutton on XP, but first look at the screenshot. I think there is something wrong with your Firefox. Maybe some extension does not work correctly with Noia4/Noia4 options.
Try to backup your setting and create a clean FF profile for testing. Use the options like shown an the screenshot.
1. default on XP
2. black XP
3. blue XP
It will be like on the picture in v1.1.7.
