hello bfb11, you could add tiles by dragging them from your bookmarks or history into the new tab page...

That did it, thanks so much!

Changes made manually on the about:newtab page are stored in prefs that you can find on the about:config page.

• browser.newtabpage.pinned stores websites that you have pinned to a tile.
• browser.newtabpage.blocked stores websites that you have removed by clicking the X button in a tile.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
