Firefox for iOS gets an opt-in network-level ad blocker
Firefox's new iPhone ad blocker is deliberately modest: it uses an EasyList-based filter and arrives disabled, with a rollout that may not reach every user yet.
Firefox for iOS can now block many third-party ads, ad trackers, pop-ups, and overlays before they load, using a filter list based on EasyList.
The limits matter: search-result ads and Firefox's own sponsored content remain outside the feature, and users must opt in.
Ad blocking arrives as a browser setting
Mozilla's support documentation says Firefox for iOS now includes an experimental, opt-in blocker based on EasyList. It works at the network level against many third-party advertising systems, trackers, pop-ups, and overlays.
The restrained scope is the story. It is disabled by default and being progressively rolled out, so not every Firefox user will see it. It also does not block search-engine ads or sponsored content on Firefox's Home and New Tab pages.
For iPhone users, the practical change is simpler than the headline: turn the feature on in Settings or from the site menu, then expect fewer ads rather than an ad-free web. That explicit boundary is more useful than a blanket privacy promise.
