There's 2 different scripts I have, you may choose whichever one you would like to use. Both scripts achieve the same goal. :P
Code:
id = "clicker"
var button = document.getElementById("clicker");
setInterval(function()
{
button.click()
}, 0)
Code:
var button = document.getElementsByClassName("btn btn-default")[0];
setInterval(function()
{
button.click()
}, 0)
