My newer modem is a faster speed. It came from my cable company. I have a MacBook Air. I can get Safari to work, but not Firefox and I need to have that browser for the work that I do.

Thank you for your help. I could not open Firefox, but now I can. My cable company is frustrating, but after a few tries everyday, I can not open Firefox which I love.
