Best way to select all friends in facebook

Here is how to do it:

1. Go to your Event, Group or page and click “Invite People”
2. Once the page has loaded you should see all of your friends, but they are not selected
3. In the box where all your friends pictures are, right click on the word “All” in the upper right corner of the box and click on “Open Link in New Window or tab”.
4. At this point, copy and paste the javascript code below into your Web browser’s address bar, then hit “Enter”

javascript:elms=document.getElementById('friends').getElementsByTagName('li');for(var fid in elms){if(typeof elms[fid] ==='object'){fs.click(elms[fid]);}}

If that first method doesn’t work for you give this a try:

1. Do exactly the same as above
2. Then paste this into the adressbar → javascript: fs.select_all()
