How can I remove social network icons from websites?

No. They aren’t ads, and apparently, other people love them because where would we be without Web 2.0?

I disabled them as well, both because of the added privacy that comes in removing them, and because it slows the loading of websites.

There’s an adblock subscription that filters them: https://monzta.maltekraus.de/adblock_social.txt

Adding it was a bit of a hassle, apparently you cannot just add any subscription anymore. I had to forge an installation link myself, let’s see if I can make on for you: subscribe.

Oh, and if some individual buttons still slip through, you could use Element Hiding Helper.

I use Request Policy. It is very effective but requires a lot of training. It pretty much says do not allow images or code from other domains to run. Example, another example.
