This update brings a major upgrade to 1Blocker’s filtering engine. Advanced rules, including scriptlets and extended CSS, now work in every filter package, not just YouTube, with support for many more scriptlet types. The result is improved blocking of adverts, anti-ad-blocking messages and pop-ups across many more websites. Make sure the 1Blocker Scripts extension is enabled in Safari and allowed on all websites to get the most out of it. YouTube ad blocking now updates alongside the rest of your filters. For Premium users, external filter lists can now include advanced rules too, with a new “Trust This List” option for scriptlets that require additional permissions. 1Blocker is also ready for iPhone Duo. This version includes several stability improvements and crash fixes. Questions or feedback? Contact us at support@1blocker.com or @1BlockerApp on X.

1Blocker enhances your browsing in Safari by blocking intrusive ads, sneaky trackers, and annoying website elements. It aims to provide a safer, more private, and distraction-free online experience, often resulting in significantly faster website load times.
Key features include blocking ads and trackers, improving website load speeds, ensuring secure and private browsing, offering advanced customization for blocking rules and hiding elements, and allowing users to whitelist specific sites. Preferences and custom rules can sync across devices via iCloud.
The app offers a free version that allows users to enable one category of blocking (e.g., Block Ads only), whitelist sites directly from the Safari extension, and synchronize whitelists across devices. Advanced customization features, such as creating custom rules for blocking URLs or hiding elements via CSS, are available in the Premium version.
1Blocker is available for iPhone, iPad, and Mac. User preferences and custom rules are kept in sync across all these devices through iCloud, ensuring a consistent experience regardless of the device you are using.
By acting as a Safari content blocker, 1Blocker provides Safari with filters in advance, allowing the browser itself to determine what should be blocked. This native integration is highly efficient, as Safari knows what to block before loading the page, leading to websites loading on average 2-5 times faster.
