Do they both say "New Tab" on yours?

I'm not aware of any built-in way to change that.

I think add-ons can change the about:blank page, but I don't know whether changing the title is one of them. If it is, the title on the tab for about:blank could be changed by this one-line script:

document.title = "Blank";

Whoops, I was thinking of the tab bar and not the address bar. Changing the address bar is not something add-ons can do. Perhaps someone has an idea for a style rule hack. This is a good site for researching such things: https://www.reddit.com/r/FirefoxCSS/

I don't realy want to go into css and addon things. and yes, I was talking about url bar, not the tab title bar, but tab titile would be also helpful

So is there a way in about:config to reaveal URL of abour:blank, about:newtab ? Thanks

I didn't find one that worked for that.
