Why is my New Tab page modified to show a Search-only box – no “or enter address”?

When I open Firefox, the New Tab page has a search box, which says “Search the web”.

But if I create a fresh Firefox profile, it looks different. The New Tab page has a box that says “Search with Google or enter address”.

Both boxes behave as advertised. On a fresh profile, the search box allows entering a website directly, e.g. wikipedia.org. But on my original profile, entering wikipedia.org runs a Google search.

What causes this difference?


  • Firefox 147.0.1
  • on Ubuntu Desktop
  • installed Firefox by default, via snap package
