I’m in firefox + uBlock on lemmy.world too, and it works fine for me - I can see on my current front page 2 posts are being blocked and the rest are showing up. Do you have any other uBlock filters going on? Are you on some page other than the lemmy.world homepage? Are you using the default UI or one of the alternate UIs?

What an insightful post 🙂

The only one of these I’ve updated since the original is the one for Ars Technica, which is now this:

arstechnica.com##:not(:not(head>title:has-text(/Serving the Technologist/))) article:has-text(/Trump|Elon|Musk|nazi|doge|maga/i)

The reason being that ‘Ars Technica’ now appears in the title of articles, while it didn’t originally, which caused the original filter to block out entire articles. ‘Serving the Technologist’ only appears on the homepage so this updated filter will still filter the homepage but display the contents of articles that contain blacklisted words.
