Make sure the problem is not your equipment. Ask your ISP to check your service.

Dear FredMcD

Greetings , hope you are fine , happy new year If you read my question , you will never give this answer , please read my question again

Happy Holidays to you as well.

So you are saying that other browsers had no problem, just Firefox? FF is using the web, yes? Just not very well?

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

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

Yes , Still same

Start your Computer in safe mode with network support. Then start Firefox. Try Safe websites. Is the problem still there?
