My chrome runs on a 2012 macbook pro. Recently, inside of the last few days, Chrome has begun opening a new tab in every chrome window when I wake. Bento for mac sierra.

The browser settings feature is another way to open new and recently used tabs quickly. Click on the settings icon -- displaying “Customize and control Google Chrome.” From here, you can open a new tab, one or more recently closed tabs or your favorite sites. You can also set your Chrome browser to ignore the “new tabs” page and instead, open with your favorite tabs already loaded. Click the settings icon, then choose “Settings,” and change the “On Startup” setting to either re-use the settings from the last session, or customize which tabs you want opened every time you launch your browser.
