If you want to tinker with a site using jQuery in the developer console but it’s not loaded, you can load it from a bookmark. Set up this bookmark in your bookmark bar so that you have quick access to jQuery on any site in the $$ global variable.

Minified Bookmark Code

javascript:(function(){var e=window.module||null; window.module={exports:{}}; var t=function(e){if(!window.console)return; if(window.console.info)window.console.info(e); else if(window.console.log)window.console.log(e)}; var n=function(e, t){var n, r, i, s; n=false; r=document.createElement("script"); r.type="text/javascript"; r.src=e; r.onload=r.onreadystatechange=function(){if(n)return; if(this.readyState && this.readyState!="complete" && this.readyState!="loaded")return; n=true; if(typeof t=="function")t.call(this)}; i=document.getElementsByTagName("script")[0]; s=i.parentElement?i.parentElement:i.parent; s.insertBefore(r, i)}; n("//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js", function(){$$=window.module.exports; window.module=e; t('$$.fn.jquery = "'+$$.fn.jquery+'"')})})()
