the symbol on the startup,that you click to go to the website is suddenly gone and I can't figure out how to get the symbol back.Thanks for any help

Which symbol do you mean? Can you post a screenshot of the area the symbol normally appears?

Do you mean your Firefox icon has disappeared from the desktop or Taskbar or wherever it normally is?

In that case, could you first confirm that Firefox is still installed by doing this:

In the search box on the Windows Start menu type or paste the following and press Enter:

firefox.exe

That should start Firefox up and display your home page (or previous session windows and tabs, if you selected that instead).

Does that work or do you get an error message?
