You're talking about the transparency of a panel, right?

Is Firefox using client-side decorations (i.e. tabe at the bery top of the window), or a traditional titlebar? If it's using CSDs, does it work if you switch it to use a traditional titlebar?

Does panel transparency change adaptively when other windows are maximized and de-maximized?

It was the client-side decors. I switched to classical titlebar and recognized, that firefox was actually not in full-screen mode (although it looked so). After really switching to full-screen, adaptive transparency worked for both, traditional and client-side decorations.

For other windows it is fine too.

Thus, I think this bug was more a mistake, and can be closed from my point of view.

Thanx,
Robby.

Oh good!

Yes sometimes windows open in a state where they have the same dimensions as maximized windows, but they aren't actually maximized. This isn't the same thing. The adaptive transparency feature should handle that case too!
