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?
I've also been looking for a way to fix/augment Chrome's Omnibar which still falls short of Firefox's Awesomebar in functionality esp. in handling items from my history.
In the same line as mlsteeve's solution, I added History Search as a shortcut item. I did so by:
Historyhschrome://history/#q=%sIt is not a perfect solution but it works well enough for my needs. Now you can quickly search your history by typing hs TAB in the Omnibar. The bonus is that your results are a little more detailed than in the URL bar.
It can never be fully disabled, unfortunately. You can clear your browser history (including all new history being cleared on session exit every time) and follow the below steps to get close to the desired results.
In older versions of Chrome:
In newer versions:
Keep in mind that the address bar shows matches from your browsing history, in addition to predictions. If you don't want to see matches from your browsing history, you must clear that as well.
Beyond that there is nothing more you can do. It is either all or nothing. You cannot modify the behavior of how you dismiss suggestions. Suggestions and autocomplete are the same service.
