In an attempt to sell advertising space in a user’s new tab page within the Firefox browser, Mozilla is launching a new platform called “Suggested Tiles” specifically for advertisers. Similar to Google using your Web search history to load related advertisements within Google Adsense placements, Mozilla will look through your visited sites within Firefox to suggest an advertiser site to visit and display it on the new tab page.

However, there are user protections built into the new feature as detailed on Mozilla’s Advancing Content blog. Users will be able to flip off the Suggested Tiles function by toggling a check box within the browser’s settings. Users can also completly avoid site suggestions by opting for a blank page when opening up a new tab within Firefox.
