Can I get the Stop button back on Firefox?

I tend to use Firefox, and I tend to let it update, so I’ve got the latest version, and it does not seem to have a Stop button. Is there a way for me to get a Stop button to show up.

By Stop button, I mean a button that will stop the browser loading a new page, so that if I accidentally click a link, or for whatever reason, want a page load in progress to stop, it will.
