Firefox for iOS now has a built-in ad blocker

Introducing Ad Blocker for Firefox on iOS

Mozilla has introduced Ad Blocker for Firefox on iOS, a built-in option that blocks many third-party ads and ad-related trackers before they load. Using Apple's WebKit Content Blocker technology and the EasyList filter list, it's off by default and can be enabled in Settings > Browsing > Ad Blocker. While it won't block all ads—site-served ads and search result ads still appear—it complements Firefox's existing privacy protections. This move addresses the lack of extensions on iOS, giving users more control over their browsing experience.

Giving people choice in how they experience the web is important to us.

    > Does ad blocking affect search engine ads?

    > No. Ads shown on search engine results pages are not blocked.

    A lot of the search results on top of Google are there to scam you, providing phone numbers for pass through services that charge $ for it, like flight cancellation:

    So this omission should absolutely be addressed, but they probably cannot because of the Google Search contract...

    I was going to give credit to the direction Mozilla was taking here after their... questionable decisions in the past few year(s).

    Only to see that this is neither generally available, nor can you use it without enabling telemetry. I don't know who makes these decisions inside Mozilla, but I just don't get it.

    It's been days (weeks?) and I'm still waiting for the option to appear for me. These "experiments" are super annoying when you are on what I'm assuming is the long tail of a rollout but the marketing/blog posts speak of the feature like it's already launched.

    If there's someone at Mozilla reading this: turn it on already! I want to get off Orion, it's so buggy, but the internet is unusable without an ad blocker.

    I was using ublock origin lite but now I've converted to wblock.

    Absolutely amazing, works inside webviews (e.g. netnewswire).

    v3 just released.

    Finally. I turned it on immediatedly. Doesn’t seem to block youtube-ads, so unfortunately I can’t uninstall Brave just yet.

    > "ads shown in search results will still appear"

    Is that for a technical reason or a commercial one?

More from this day
