Firefox Inline Autocomplete

Mar 5, 2007 | posted in: nerdliness

To turn on inline autocomplete in the Firefox web browser…

Enter about:config in the URL field
Right-click on the page and create a new Boolean value
Enter browser.urlbar.autoFill as the preference name (note, case-sensitive: ‘F’, not ‘f’)
Set the value to true

Why this isn’t exposed in the preferences I’ll never know.
