This has happened often, I've had Norton Identity Safe on several different FF versions and it works fine, no worries. Suddenly I open my browser--I've preferred FF for years now--and my Norton bar is gone, the add-on directory tells me it's not compatible. It was the day before. Tonight it happened, and it was the hour before. I thought it was my computer, then my Norton vault, so I uninstalled and reinstalled Norton after having done scans and optimizing my computer with Webroot. I tried several different FF versions from Old Apps and none of them worked with Norton Identity Safe--this had never happened before. I had always been able to find one that would enable this program to work. I now have a sadly unhappy cat who wanted some bonding time, and a computer I want to pound with a blunt object--but it's all I've got, cyberwise. Instead of cat-time, I'm downloading FF and wishing. And growling. And the Ceiling Cat is not happy. Please advise. Which program is the magic one?
