Firefox is one of the easiest-to-use browsers available on all devices. One of its ease-of-use features is the URL autocomplete.

The causes for the failure vary from wrong browser settings to broken profile files. Irrespective of the reason, this guide will show you how to fix the issue and help you get back suggestions in your address bar.

Use a more stable browser if you keep having problems with Firefox. We recommend Opera as an alternative because it’s fast and less prone to errors and bugs.

This browser has the autocomplete feature pre-enabled when you install it, and you can easily disable it or customize its settings to your own liking.
