I tried to Google it but I could not find a solution to my problem although I

tried most of the suggestion that I found through my Google search



Uninstalled and installed Yahoo


Associate HTTP and HTTPS to firefox


Enable pops up



Thanks


Edit : I realized now if I want to open a saved html file same message pops up
