Hope I helped!

Kind regards,

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

I AM NOT A COMPUTER TECH. AND ONLY KNOW LIMITED FUNCTIONS AS USUAL THERE IS NEVER JUST A STRAIGHT FORWARD ANSWER WHEN IT COMES TO ANYTHING TO DO WITH THE COMPUTER. SENDING ME COPIES OF ALL THESE LINKS IS NOT WHAT I WANTED TO HAVE AS A RESPONSE. SORRY I EVEN ASKED!

We would like very much to tell you exactly what the problem is and how to fix it. But we don't know what the real problem is. That is why we sent you those links.
