You are correct! I tried that and all was good, AFTER I reset Firefox. I was a little hesitant to do that, for fear of not having everything showing back up, but Firefox didn't take anything away........and it also told me I had to reinstall Flashplayer.........when I did that, all was well. Thank you so much for responding so quickly.
My computers are so important to me for several reasons; I am in animal rescue and I need the internet to help save those who suffer cruelty, who are lost, or dumped by their uncaring owners.....and for so many other good reasons. :)
