Tool Bar is HUGE

Not sure what happened. I use Chrome Version 37.0.2062.124 m and when I rebooted my computer my tool bar up top is HUGE.  I can use CTRL and my scroll on my mouse to make smaller my page I am viewing but the Vault, share via facebook and everything up on that line is so big...not sure what to do .

Also can I get rid of that Share via Facebook ? I never would want to share something with FB.  

 

Thanks !
