This really doesn't require a heavy jQuery dependency. I also don't know why the font related style changes are necessary. You could rewrite this script to be as simple as: const me = document.querySelector("a#me").innerText; const header = document.querySelector("span.pagetop"); header.innerHTML = header.innerHTML + "<a class='myaddons' href='https://news.ycombinator.com/submitted?id=" + me + "'>| my posts |</a>"; header.innerHTML = header.innerHTML + "<a class='myaddons' href='https://news.ycombinator.com/threads?id=" + me + "'> my cmts |</a>"; Much more efficient and does the job without the heavy jQuery dependency. I do commend your initiative though, and I'm sure many users will get much use of this.
