When you have made a Facebook page and you have a lot of friends, you will need to invite each one by choosing them from a list and it is a hassle going through them all one by one.
Here is the bookmarklet to "Select All Friends" and invite them to Like your Facebook Page, within a second, in one easy click!
Copy this into a new bookmark and click it when you are at the Friend Selection area.
