I have been wondering where URL Inline Autocomplete was in Firefox. It’s something we’re very used to seeing in IE.
Here’s how to enable Inline Autocomplete in Firefox:
1. Enter about:config in the URL field
2. Right-click on the page and create a new Boolean value
3. Enter browser.urlbar.autoFill as the preference name (note, case-sensitive: ‘F’, not ‘f’)
4. Set the value to true
