Go to the Privacy tab (i.e. \Firefox\Options\Options) and for the Location Bar, choose "History and Bookmarks" (using the drop-down arrow).

Next, go to the Advanced tab and under the General sub-tab, check the box that reads "Search for text when I start typing". Save and restart your browser.

Hope that works.

Thanks. It works fine now. I had disabled it, got to missing it and forgot how to get it back. Thanks again.

You're welcome...good to know you got it working.
