"... i tried to go to control panel - internet options - and i've changed the home page address over and over again and nothing happened."
By doing that you will set home page for Internet Explorer, and not for Firefox.
To set home page for Firefox, open it and go to Tools>Options> General tab> Home page. Here you can set any other page you would like to show at FF startup, or delete www.bsplayer-search.com as your home page.
There is really NO need for regedit, ccleaner or any other program to remove bsplayer-search.com showing as a home page of your web browser, because it can be removed very quickly and easily from the browser itself. (IE, FF, Chrome...)
