Chrome almost always autocompletes text entered on Omnibar. I set Firefox's "browser.urlbar.autoFill" to "true" so it autocompletes the text sometimes, but not as often as Chrome's Omnibar.

How do I make it autocomplete just like the way Omnibar does it?


You could try this addon.


Try Prospector - Speak Words.

This restartless add-on helps you easily get to sites that you frequently visit by typing just a few letters in the location bar and having Firefox fill in the rest of the word as well as selecting the first result. From there, just press [return] to go to that page!

  • Finally, something that works for me! Haven't used it long enough, but it does auto-fill the superbar with the rest of the first result – AllanCaeg Jun 20 '11 at 8:32
  • Except typing goog and enter takes me to maps.google.com on my browser. That, plus a couple of other annoyances, made me uninstall. – David Ryder Feb 28 '12 at 16:36

A very late reply

Firefox 12 autocompletes url in the address bar. Firefox 12 is now in aurora. Interested people can download it from here.


Type about:config, answer that you will be careful, and then search for keyword.URL

Typing the following string there will make Firefox's address bar behaviour look a bit more closer to Chrome's:


and set keyword.enabled to true.

See http://support.mozilla.org/en-US/questions/759303

To make Firefox look even closer to Chrome, you might also consider downloading the theme https://addons.mozilla.org/en-uS/firefox/addon/fxchrome/ as well as putting the downloads on the bottom bar, just like Chrome does: https://addons.mozilla.org/en-US/firefox/addon/download-statusbar/

Tested on 16.0.1 on a Mac.


Find a term where it doesn't work as well as in Chrome and file a bug report.

  • Hm. That shouldn't stop him from filing an enhancement request? – Aaron Digulla Apr 26 '11 at 19:27

I know it isn't exactly the answer you are looking for, but you could always just press [TAB]. Seems almost as fast as autocomplete.

Or you could wait for FF12, when this behavior will come shipped.


As of 2019, the prospector extensions and the other options mentioned are not available any more.

A solution was mentioned on Reddit. If you got to Library and then Bookmarks, Show all bookmarks (alternatively press Ctrl+Shift+o), each bookmark has a keyword entry. By adding the short version of the website, Firefox will proceed directly to the bookmarked URL instead of the incomplete URL.

See screenshot.

You need a shortcut for each substring of the desired URL:

  • e
  • ex
  • exa
  • exam
  • ...
  • example.com
