Removing the default search engine Ask.com from Mozilla Firefox

Can be intentional or not, but mostly not intentional, your default browser search engine became to Ask.com, this usually happens because we are installing the toolbar or freeware application that there was a relationship with Ask.com, so that you become the default web search to ask.com.

If you feel bored or annoyed by the existence of this ask.com the search engine, as I feel, yes it should be removed and replaced again with google.com.

In Firefox browser, to eliminate them and restore the default search engine to google.com follow a few simple steps below:

-Open your firefox browser
In the Address bar, type about: config click Go or press Enter,
-Click I'll be careful, I promise

-In Filter column, type keyword.url

Double-click keyword.URL
-Replace String Value, which was http://www.ask.com ....
become http://www.google.com/search?ie=UTF-8&oe=utf-8&q =

-Click OK,

Now your Firefox default search engine Ask.com is no longer, but Google.com.
