no more capture capability
Several captures tools, like FastStone, have a 'sliding capture' feature, which unwrap the window content before capturing it. After updating to 4.0, the capture includes the title bars and overwrites the capture.
I think that the root cause is the new program design, because the content window is no more isolated from the Firefox window.
