Mozilla quietly rolled out Suggested Tiles, its built-in ad product for Firefox, in early August; currently not getting paid for them

Context & Ripple Effects
Mozilla first flagged this in May, when it announced sponsored Suggested Tiles built on users' browsing history, and the ZDNet report confirms it went live quietly in early August — with the notable detail that advertisers aren't paying for placements yet, making this a live distribution pilot rather than a revenue line.
The arc matters because Tiles is a test balloon, not a destination: by December Mozilla would end the Tiles experiment entirely and pivot to 'content discovery', and by 2018 it was back with Pocket-powered sponsored story recommendations in new tabs. This report captures the experiment mid-flight, before anyone knew which format would survive.
First-order effects
- Firefox new-tab users are now seeing sponsored Tiles selected from their own browsing history, meaning the browser's default surface has become an ad inventory without an explicit opt-in moment at rollout.
- Advertisers in the pilot get free reach while Mozilla gathers engagement data, so the company is subsidizing the test with its most valuable asset — default placement — before pricing anything.
Second-order effects
- If Tiles' click-through disappoints, Mozilla's fallback is already visible in its later moves: content discovery via acquisition, culminating in the Pocket-sponsored new-tab product, rather than selling raw tiles to brands.
- Rival browsers face pressure to answer the question Mozilla is testing — whether the new tab can be monetized natively — turning default-page real estate into contested inventory across the browser market.
Third-order effects
- The pattern points toward browsers consolidating around curated-content monetization over direct-sold display ads: Mozilla killed Tiles but kept iterating until Pocket gave it a format that blended sponsorship with editorial recommendation.
- If the structure holds, browser vendors' economics shift from search-deal royalties alone toward owning native ad surfaces inside the product itself — with privacy positioning becoming a competitive lever for whoever runs history-based targeting.
The trend: Browsers are becoming native advertising surfaces, with Mozilla treating the new tab as a monetization lab — trying Tiles, killing it, and rebuilding the idea as sponsored content.
