Firefox now blocks ads on iPhone. Is it good enough?

Firefox is rolling out built-in ad blocking on iPhone, which sounds like an easy win for anyone tired of ads and trackers. And in many cases, it is: the feature can block plenty of third-party ads and tracking without asking users to install anything extra. But it also leaves search ads, first-party ads, and Firefox’s own sponsored content untouched.

So the real question is how much protection and control you actually get. For some users, the built-in option may be enough. Others may want stronger filtering, more customization, or protection beyond a single browser. And on iPhone, that choice is still shaped by Apple’s restrictions on what browsers and blockers are allowed to do. We compared where Firefox stops, where AdGuard goes further, and how much choice iPhone users really have.

Firefox, privacy, and the fine print

Why was Firefox using an ad tracker?

Mozilla quietly used a third-party tracking tool for years to measure which ads brought people to Firefox, then removed it without much explanation. For a browser built around privacy, both parts of that story raise questions.

Why it matters

When Firefox’s “never sell” promise disappeared

Mozilla once answered whether Firefox sold personal data with a reassuring “Never have, never will.” That wording later disappeared as its privacy language became more ambiguous and its involvement in advertising grew. The legal explanation may be complicated; the trust question is much simpler.

Firefox chose a different path for ad blockers

When Chrome moved toward tighter limits on extensions with Manifest V3, Firefox made a different choice: support the newer extension standard without giving up the blocking tools powerful ad blockers relied on. It showed that restricting ad blockers was never the only technical way forward.
