Thank you Aris Rated 5 out of 5 stars
Many thanks for your kind and comprehensive answer with explanation. Shame that it is not possible.
There is a Metro+ project on deviantART, that may become what Glass fans want. There is no release date yet.
Great but some suggestions and kind ask for Win8 Rated 4 out of 5 stars
Hey, thans for your great add-on ever exist for Firefox. It's beautiful and give us shining design for our FF.
But I have one great ask for you about WIn8. Everything works seamlessly but only one thing upsets me very hard. When I'm switching to the Download window or any Firefox settings, I'm getting temporarily losing of all glassy shine...when I'm focusing to the main Firefox window, all returns but this is very annoying and this moment it is very ugly...Can you something improve it for Windows 8 (I'm using Windows 8 Pro for my desktop PC?
as much I would like to solve this issue, I can't. Window behavior in Windows 8 (final) is just like that and not changeable by Firefox or an add-on. This is one "feature" of the new Windows 8 gui.
I hope someone releases a real AeroGlass gui/theme for Win 8 some day, so GMF and GMB were fully compatible to Win 8 again.
GlassMyFox and GlassMyBird officially only support Windows 7 and Vista, while Win 7 is the preferred one with best "Glass" quality.
