On desktop I got tired of facebook always suggesting something. Whatever I clicked, commented or watched, there would come up some content asking for my attention. No! And all the people I could add as friends. No! And groups to join or create. No! And pages to like. No! And… Just no!
So I cooked up a userscript to address the issue. I use it with chrome with tampermonkey. Since privacy could be a concern, the script is self contained, does not go out of the DOM, does not send anything anywhere, does not call anything not on the page, so does not check for updates, nothing. Thus there is no way it could steal data.
