While this feature is available on many third-party apps, it’s not on the browser. However, since you’re already using an ad blocker, you can use it to filter out content as well.
To filter out posts with certain keywords, go to your custom filters and add this code. For example, to hide all posts containing the word “Elon”:
lemmy.world##div.post-listing:has(span:has-text("/elon/i"))
If your instance is something other than lemmy.world, just replace it with the correct domain.
To filter out comments, use this:
lemmy.world##article.comment-node:has(div.comment-content:has(p:has-text(/asshole/i)))
To add more keywords, simply duplicate the code and replace the keyword with another.
Of course you need melon news. You ALWAYS need melon news. I, for one, want as many big, juicy melons on my feed as possible.
I could have said felony, but that refers to the same social group as Elon, so they’d probably want to censor it anyway.
