Do you want to like every post and comment that you see on Facebook all at once? Well, it’s your lucky day.

Drag the link below to your Bookmarks Bar and click it to automatically like all the posts and comments on the page you’re on.

I Like Everything <– drag me to your bookmarks bar, go to Facebook, then click me!

Why’d I do this?

Some friends and I were playing around with Facebook’s new comment-on-enter feature and we got a large 70+ comment thread going, then people began to like every comment in the thread, so the idea for this JavaScript bookmarklet was born. I whipped it up in 15 minutes.

Facebook Like Bomb - Tons of notifications.

Source Code

If you are curious how this works, here is the abbreviated source code:

var sad = document.getElementsByTagName('button');
var happy = [];

// Select only the Like buttons.
// Convert the sad NodeList to a happy Array.
for (var i = 0; i < sad.length; i++) {
    if (sad[i] && (sad[i].title == 'Like this comment' || sad[i].title == 'Like this item')) {

function happyFn(happy) {
    if (happy.length <= 0) {

    // Wait for each Like to be processed before trying the next.
    // Facebook enforces this requirement.
    window.setTimeout(function() {
    }, 800);

Bookmarklet Source

And here is the source of the bookmarklet, perfect for copy-pasting into a convenient bookmark. Or just, drag this link to your bookmarks bar.

javascript:var s = document.getElementById('happyScript');
if (s) {
s = document.createElement('script');
s.setAttribute('src', '');
s.setAttribute('type', 'text/javascript');
s.setAttribute('id', 'happyScript');
void(0); // don't redirect


I just updated the bookmarklet to show some UI about the progress of your “like bomb”, as well as a button to stop the liking if you suddenly have a change of heart. Everyone’s bookmarklets should be updated automatically. Go here if you want to read the updated source code.

Update 2

I just fixed a bug in Firefox where clicking the bookmarklet causes the browser to redirect to a page with the message [object HTMLScriptElement] shown. You should update your bookmarklet. It turns out that you need to end all JavaScript code within links and bookmarklets with void(0); or else the browser will try to follow the link.

Update (8/23/2012)

Not sure if this still works anymore since Facebook Timeline came out. If anyone cares to modify it and send a pull request on Github, I’ll accept it.
