Because tabs are a still rather new feature, some people may make a mistake chosing 'File->Quit' and closing the whole browser, not thinking that many tabs are opened and will also be closed. In the case one choses Quit, a dialog should popup and warn the user that many tabs are opened. Dialog suggestion: ------------------------------------------------------ | Warning - Quitting application ? | | | | Several tabs are opened. | | Quitting will close them all. | | | | _______________ _________ | | | Quit Anyway? | | Cancel | | | |______________| |________| | | | | ( ) Do not show me this dialog in the future. | |____________________________________________________| I put severity as major as there is an obvious risk of data loss. I was sure they would be a duplicate but couldn't find it searching for 'quit' and 'quit tab'.
