I'll try my best to explain ,but sorry for my poor English .
I installed git swfdec (rework the way we call swfdec-test again master) and swfdec-mozilla(append the flashvars to the initial file's url master) if I open a tab contains a flash in firefox3 ,then close the tab, the tab will close,but the swfdec flash window will be a separately window which name is "unnamed" ,and if close this swfdec flash window
firefox will crash immediately or crash when open a new tab contains a flash . terminal gives out
"(firefox:27292): Gdk-WARNING **: GdkWindow 0x1401a32 unexpectedly destroyed
The application 'firefox' lost its connection to the display :0.0;
most likely the X server was shut down or you killed/destroyed
or"firefox X IO fault"
