hello dolphingirl419, please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and to a full scan of your system with the security software that you have in place. [[Remove a toolbar that has taken over your Firefox search or home page]] then go to firefox > help > troubleshooting information > "profile folder - show folder". a new window should open up - in case it does contain a file named user.js, please delete that and restart the browser. you could also install the [https://addons.mozilla.org/firefox/addon/searchreset/ searchreset addon] afterwards, it will revert the settings that those kind of adware usually modifies to their default.
