Click on it and move your mouse pointer down to tools. To the left of the tools choice right click on extensions.
Any extensions that refer to something other than you have yourself have installed - or any thing that looks like msn or bing in the name need the trash can next to it clicked.

That should fix it.

If it doesn't, you'll have to click on the google menu button again, and move your mouse pointer down to settings and click on it. After the settings page opens, scroll down to show advanced settings and click on it.
Then finish scrolling down to the bottom of the page and click on reset browser setting to their original defaults. After this you will need to reinstall the apps that you want back on your google browser.

You just go into your browser setting and then set page on new tab event.
