The thumbnails on the about:newtab page are generated from the cache, so if the page is not in the cache or otherwise can't be rendered as a PNG image then you will get an empty box.
Do not use Clear Recent History to clear data when you close Firefox.
If there is no history then you get an about:newtab page with empty boxes.

Hi glory_h

Can you please start a new thread for your question?

Then you can provide more information like your operating system and installed extensions and installed plugins.
