What about an exit popup ?

all is well what about the exite button ,,,,,or esc key when user ignores

Hey! I could use a little help…I would like to add an exit popup to my front page on which are my posts. I have an exit popup plugin and when I edit a page or post i have the option to activate the plugin but for my front page I don’t have a separate page in the pages section. Some advice?
Thanks
