If you're a hypothes.is user on Firefox, you'll be familiar with their little bookmarklet that tacks the annotation interface onto the side of any webpage.

Well, almost any webpage. Sometimes the settings will block the JavaScript from being able to execute right. I've got a few here where you can see it's been useful to me.

Tampermonkey to the rescue! That same bookmarklet code just gets shoved in a script.
