Blocking elements based on content across all sites and regardless of element type


New Member
Hello, I was looking at the documentation and I saw that it's possible to block elements based on content with the :contains() selector, and I've seen another post about how to do it for reddit titles, but I was wondering if anyone knows how to achieve this for all element types across all websites.

The documentation says div:contains(abc) should work, or perhaps *:contains(abc), but I haven't managed to get either of these to work.
Any tips would be appreciated
