Mozilla and uBlock Origin ad-blocking developments

Overview

The landscape of ad-blocking technology is shifting as developers and browser manufacturers adjust to technical challenges and market changes. The uBlock Origin team announced it would cease active maintenance of filters specifically for Facebook, citing the difficulty of countering Facebook’s methods to evade pattern matching, such as breaking up the “Sponsored” label into non-visible elements.

Maintainers noted that Facebook developers frequently implement countermeasures that render fixes obsolete within hours, often by altering element names or serving ads through first-party infrastructure. Experts suggest this retreat carries security implications, as ad blockers play a critical role in preventing users from encountering malicious or scam advertisements. While services like AdGuard may still provide coverage, uBlock Origin will no longer prioritize updates for Facebook’s evolving delivery methods.

Concurrently, Mozilla has moved from experimental stages to a more integrated approach for Firefox on iOS. With the release of Firefox 155, the browser now features a built-in, optional ad blocker for iPhone, iPad, and iPod touch. Utilizing Apple’s WebKit Content Blocker technology alongside the EasyList database, the tool targets third-party advertising networks, trackers, pop-ups, and intrusive video overlays by filtering content before pages fully load.

This feature is turned off by default and must be manually enabled via the browser settings under the “Browsing” or “Surfen” section. Mozilla clarified that this native integration is intended to complement, rather than replace, existing third-party extensions. However, the tool has specific limitations: it will not block advertisements within search engine results, ads served directly by a website, or sponsored content on Firefox Home and New Tab pages.
