Mozilla Firefox 41 introduced live search suggestions in the address bar of the browser. While many people might like this change, there are some who do not want to see those suggestions in their browser. If you want to disable this feature, follow the instructions in this article.
Mozilla Firefox users might be familiar with its live search suggestions. When you type some text into the Firefox search box, the search suggestions feature sends your query to the search engine and returns suggested words to refine or complete your search.
This is quite useful. Even if Firefox still has a dedicated search box, many users perform the search directly from the address bar because that's the way it is in all other browsers. With Firefox 41, Mozilla has added live search suggestions for the address bar as well.
