Welcome to the Q&A Forum

Hi there - Kristina from Moz's Help Team here. Thanks for reaching out to us and I'm sorry to hear you are experiencing issues with Mozbar. Since this is an extension of your browser, it may be difficult for us to isolate as the toolbar will rely on your personal settings in the browser. Here are somethings you can try to get it working: Make sure you are not in incognito mode Disable/un-install all other extensions leaving just Mozbar to isolate Re-install Chrome Check to see if the address bar is hiding the extension icons: http://www.screencast.com/t/7cLHKkOP Disable any software firewall or security apps As always, you can reach out to our team in the future with any product-related questions by sending an email to help@moz.com or clicking on the little blue chat icon on the lower half of your screen while in the tool. I hope this helps but please let me know if you're still needing assistance. Thank you, -Kristina
