I had Mozila Firefox installed ina Windows 10 Pro platform and worked ok. Suddenly, it stopped openning. I uninstalled it and downloaded Mozila Firefox 64bits ver 57, reinstalled it and when I click on the icon nothing happens. I went to Task Manager and I waw that Firefox is running in backgroud mode. I have searched for solution and only found one suggestion that I have not tried which is to uninstall Norton and install it competitor.
I am a Norton customer since 1986 when Norton Utilities was the best tool to have. What shoud I do?
