Facebook ads are so hard to block that uBlock Origin stopped filtering them - Neowin

uBlock Origin is an open-source browser extension that blocks ads and tracking elements on web pages based on publicly available filter rules. Since August 2018, the GitHub repository 'uAssets,' which contains the filters, has consolidated reports and suggested fixes for ads appearing on Facebook into a single issue.

On August 5, 2026, uAssets maintenance member stephenhawk8054 announced in this issue that they would no longer support Facebook. The issue was labeled 'wontfix' and closed on August 9.

stephenhawk8054 criticized Facebook as a 'hostile and offensive site to users,' claiming that Facebook developers are checking publicly available ad-blocking filters and taking measures to make ads reappear. He further sarcastically remarked that 'all developers earning over $1 million a year are doing is these kinds of ad-blocking measures,' and urged users to strongly protest against Facebook. He also stated that accepting Facebook's stance and continuing to use it is 'the worst thing a user can do.'

This decision does not mean that existing Facebook filters will be immediately removed. Custom filters created by users and filter lists distributed by ad-blocking service AdGuard will remain available. However, if existing standard filters become ineffective due to changes on Facebook's side, the maintenance team will not fix those filters.

On the social forum Reddit, users who participate in filter maintenance have posted comments such as, 'Even if you fix a filter, it sometimes stops working within a few hours, and the longer you spend fixing it, the greater the burden of having to redo it.'

Another maintenance member commented that 'only about two people are primarily responsible for updating the standard filters for uBlock Origin, which is used by tens of millions of people, and the number of contributors has actually decreased rather than increased.' The update work is done in their spare time, making them prone to burnout, and this is only the second time in over 10 years that they have stopped updating filters for specific sites. It's not that they 'lack motivation,' but rather that the burden of constantly making adjustments to keep up with Facebook's changes is simply too great.

On the other hand, regarding the response of discontinuing Facebook use, some commented that 'family and work connections are concentrated on Facebook, and it is difficult to ask elderly users in particular to switch to another service.'

Hacker News , a social news site, has pointed out that 'Given Facebook's precedent of forcing uBlock Origin to abandon support, other websites may start using the same method.'
