how do I disable url bar suggestions?

Whenever I search using the URL bar at the top, it comes up with suggestions from my history, I hate this and it's only started happening after updating Firefox?? How do I turn it off? I tried to turn it off in about:config and in settings but it's still happening, how do I stop it suggesting history when I use the URL bar to search? On Firefox Android, never used to happen and doesn't happen on my computer
