I recently purchased a MacBook Air and had to install Google Chrome to use Webex and Hangout calls. Post installation, each time I started/restarted my MacBook, I was greeted with a blank Google Chrome window. This functionality is great if Chrome is your primary browser but irritating if you primarily use Firefox like me and use Chrome for specific activities as needed.
After going through various forums, I finally arrived at the below steps which are simple and straight forward: 1. Goto System Preferences » Users & Groups. 2. Click on the Login Items tab for your user name. 3. You will see an entry got Google Chrome, remove the entry by first selecting Google Chrome and then clicking on the - (hyphen/minus sign) at the bottom. Do not make the mistake which I did of clicking on the checkbox and expecting it to be removed, you need to click on the minus symbol at the bottom to stop it.
After more than a month of struggling with it, I was relieved to finally get rid of Chrome from popping up each time I started the MacBook Air. Yay!
