Chrome is the world’s most popular browser, and unfortunately, Google wants you to use its shortcuts. Removing "Most Visited" pages here requires a few different strategies depending on how aggressive you want to be.
Click the Gear icon in the top-right corner of the New Tab page. Uncheck the box labeled Shortcuts . Why Should You Remove Most Visited Pages?
Right-click (or Control-click) on any icon under "Frequently Visited" and select .
If you clear your history, you clear the "Most Visited" list. However, this is temporary. As soon as you start browsing again, new thumbnails will appear.
