Reducing the number of results in the address bar :
After installing this add on, if you want less number of web results to be displayed then follow this easy steps :
1. Enter about:config your address bar. Ignore any messages or warnings.
2. Type browser.urlbar.maxRichResults in the Filter field
3. Double click on it, a small box opens with some number (it was 12 for me), just limit it to 5 and click on Ok.
This way you can reduce the number of results in your firefox address bar.
