I have this problem where Chrome only shows my previous queries/urls and won't show predictions. It was like this all the time I'm using Chrome, which is my primary browser for last 5+ years. I've just recently noticed that predictions from Google is a feature when using another computer where Chrome was running out of the box, i.e. without syncing settings from my profile.
I've searched and only thing I've found is that I should have the option "Use a prediction service to help complete searches and URLs typed in the address bar" checked, which I do. If I log out as Chrome person, it works, but as soon as I log in and settings sync, it stops working again.
I guess resetting the settings would be an option, but I'd really like to avoid doing that as I don't want to configure everything back. Any other solutions or suggestions?
