Resolved Cannot choose "Custom URL" in Options> New Tab

I reformatted and reinstalled Windows 10 last week from scratch and installed Firefox and I am having a problem with Tools> Options> Home> New Tab. My choices are "Blank Page" and "Firefox Home (Default)".

Before formatting and reinstalling, I had the option of a custom URL for new tabs. How can I get this back.

In case it matters, the custom URL I want is the Google search page that is otherwise blank.

 

Set the home page in FF to Google.

 

It's already set to that.

 

It seems that it is no longer available in FF Ver.720.0

 

I hope someone has or will come up with a hack.

Thanks, I must have had that for a long time, so long I forgot it was there.
