"Even so, not everyone wants to see them. And continuing in Mozillaâ€™s pro-choice, pro-privacy tradition, Firefox makes it easy to disable the New Tab page ads.
Just open a new tab, then click the gear cog in the upper right-hand corner of the page. Three options appear in a drop-down menu: Enhanced, Classic, and Blank. The new ads will only appear if youâ€™re using the Enhanced option, which is enabled by default.
Selecting Classic will force the New Tab page to only display sites from your browsing history, while Blank is, well, a blank page. No aggregate data is collected once you disable the Enhanced tiles, either.
And thatâ€™s it! Once you make that one, simple change, ads are gone forever from Firefoxâ€™s New Tab page. But consider what youâ€™re doing before you flip the switchâ€”Mozilla needs money to continue developing Firefox and fighting for the future of the open web, and the ads truly arenâ€™t much of an eyesore."
