You listed FireFox as the browser - I'm providing Internet Explorer settings because the behavior you are describing is IE not FireFox... I will tell you that FireFox can GET that behavior by installing some Extensions - but those extensions are Google search only.. And you'd have to change the extension to change the Search functionality of them...
were do you find the setting for makeing the address bar search(give you a search results list)instead of going to the most likely sight.
In Internet Explorer, from the Tools menu, choose Options. Then click on the Advanced Tab...
In the Advanced Tab - find the area titled "Search from the Address Bar" - then find "When Searching".
Choose the 3rd option - "Just display the results in the main window"
how can you tell it what search engine to use besides the bar on the right cause i want it to search in the main bar.
Assuming everything is setup as defaults...
When you click the Search button you will get the side-panel with the little mutt animation asking you what you want to do... (Note even if you don't use the animation this will still work)
From here - find the "Change Preferences" link and click it.
Then find the "Change Internet Search Behavior" on the next screen that pops up (it should be option 4)
Choose to use the "Search Companion" or "Classic Internet Search"
Then below - choose your default engine... Click ok.
Click the search button on the toolbar to close that pane.
Now when you do the address-bar search it should use the search engine you chose.
(NOTE: This works for me as I just tested it)
