After downloading the stable version of firefox 3 during the firefox download day, i had a problem with two things. First goes to the themes my sister and i use. Most are not updated and compatible with firefox 3 and so we had to delete them. Good thing one of my favorites which is the blue cats flavor is updated and very much compatible. Second is the smart location bar, a feature that automatically adds other urls upon typing something in the address bar which really annoys me. I tried searchingthe options and all menu just tp find how to disable it but i found nothing. So i checked the Firefox Support website and there – among the top topics in the main page is “How to disable the Smart Location Bar“. Finally, i found the solution to my problem 
Here are the steps i found and followed to disable it:
1. In the Location bar, type about:config, and press ENTER. The about:config “This might void your warranty!” warning page may appear. Click “I’ll be careful, I promise!” to continue to the about:config page.
2. Search for the preference browser.urlbar.maxRichResults.
3. Double-click the browser.urlbar.maxRichResults preference and enter a value of -1. (initial value is 12)
4. From the menu at the top of the Firefox windowbar, select File and then select the Exit.
5. Restart Firefox again.
Now when you type in the Location bar, no list of results will be shown. To re-enable the autocomplete list, follow the steps above, but set the value to 10 (which is the default value).
