Mozilla is launching Suggested Tiles, a new platform for advertisers which will scan users browsing history to suggest advertising websites. Mozilla says, Suggested Tiles doesn't share personal information, or use third-party data or cookies to deliver its experience. Instead, it's completely user-controlled.
The feature can be turned off via Firefox's settings if users doesn't want to see the suggested websites. Personal data will not be supplied to advertisers, but rather anonymous clustered data will be given to them. Mozilla will have the final approval over the suggested websites that will appear on the "New Tab" page.
