how do i turn on auto complete

Hi Anthony, both of those are "on" by default, but you can check your settings on the Options page, Privacy panel. "3-bar" menu button (or Tools menu) > Options In the left column, click Privacy. If the selector says "Firefox will: Remember history", change that to "Firefox will: Use custom settings for history" so you can see the individual settings. There usually is a checkmark for "Remember search and form history" but, if not, go ahead and check that. Toward the bottom of the tab, there are checkboxes for whether to show different categories of data on the address bar autocomplete drop-down. More info in this article: [[Settings for privacy, browsing history and do-not-track]] ---- Now... if you are missing old history, of course, there's nothing to show. Do you know if there is any backup of your old data that you might be able to restore?
