find a bunch of stuff on the page and click on them

gistfile1.txt

var divs = document.querySelectorAll('.button'); [].forEach.call(divs, function(div) { div.click();});

I've also used the same approach in an interval to banish adverts that are on the page and continue to appear in 'infinite scroll pages'

e.g.

setInterval(function(){
var advert = document.querySelector(".dismiss-advert");
if(advert){advert.click();}
},200);

a 'for' loop version would be:

var divs = document.querySelectorAll('.button');
for (x = divs.length - 1; x >= 0; x--) {
   divs[x].click();
}

For loop which doesn't work in reverse:

var divs = document.querySelectorAll('input.toggle');
for (x = 0; x < divs.length; x++) {
   divs[x].click();
}

Working in reverse can be useful when you are 'deleting' or the length changes over time, here my action doesn't change the length so I can start at the top and work down.
