This can happen if adware  Genieo is installed without your knowledge. Removing it will help,
1. Download and use free AdwareMedic to remove the adware
    http://www.adwaremedic.com/index.php
    Install , open,  and run it by clicking “Scan for Adware” button   to remove adware.
    Once done, quit AdwareMedic.
               or
    Remove the adware  manually  by following the “HowTo” from Apple.

2. Safari > Preferences > Extensions
     Turn those off and relaunch Safari to test .
     Turn those on one by one and test.
Note:
  If you don’t have another browser installed,
startup into SafeMode, log into your account, launch Safari
and download  AdwareMedic or the removal instructions from Apple.
How to start up into Safe Mode?
Shut down the computer.
Press the power button. Immediately after you hear the startup sound, press and hold the Shift key.
The Shift key should be pressed as soon as possible after startup,but not before the startup sound.
Release the Shift key when you see the Apple logo on the screen. Startup will take longer than usual.
Launch Safari. Follow the  steps posted above to remove the adware.
Once done, quit Safari and restart the computer from  in the menu bar.
