When I turn on Firefox now, Yahoo pages, Yahoo sign-ins, and full screen advertising come up instead of my email page. Sometimes as many as three sign-in boxes appear asking for me to create a new email account. A check box is available to "keep me signed-in" is present, but it never 'remembers' to do so. It takes much time for these pages to appear, thus slowing my computer considerably. Why this INVASION? I didn't choose Yahoo; I was happy with the previous setup. Neva
