What happened
Mozilla is progressively rolling out an experimental, off-by-default ad blocker in Firefox for iOS, using an EasyList-based filter list to block third-party ad networks, trackers, pop-ups, and overlays. It notably does not block search result ads from Google or Bing, nor sponsored content on Firefox's own New Tab Page, and Mozilla acknowledges some ads won't be caught by the current filter list.
Why it matters
If you ship web content or ads, expect a subset of iOS Firefox users to start blocking third-party ad infrastructure via this toggle—though the search-ad exemption means Google-served search ads remain visible. For builders, the more actionable signal is the Adblock Plus warning that conversational AI advertising is coming, which will be harder to detect and block than traditional display ads.
Discussion angle
The search-ad exemption raises the question of whether browser-vendor ad blockers can ever be fully trusted when the vendor's revenue depends on the very ad networks they're supposed to block—worth comparing with Brave's approach.
