If you’ve not, first check the post to make Bing your default search enigne in IE, Firefox or Chrome browser. This post shows “how Bing’s integration with both Internet Explorer 8 and Firefox provides quick access to information”:
-When typing queries in IE8 Search Box, Bing returns auto-suggestions, including Instant Answers. These suggestions are available in English only in the markets. Bing accelerators enable you to access your favorite online services no matter where you are on the web. IE8 Web Slices enable you to monitor information that changes periodically. We have Web Slices available for you to track Weather, Finance and Traffic.
-When you type a query in Firefox search box, Bing will return a list of suggestions based on what you have entered. Bing is based on the Open Search standard and we use the JSON interface supported by Firefox to retrieve auto-suggestions.
