How does one select all friends when trying to invite them into groups, etc.?
Select All Friends in Facebook
facebook;friends
Click on the invite button, paste this code in to your address bar: javascript:elms=document.getElementById('friends').getElementsByTagName('li');for(var fid in elms){if(typeof elms[fid] === 'object'){fs.click(elms[fid]);}}and hit enter. All friends will be selected, enjoy!
