Kickstarter backers who have missed out on an early bird reward level can still get these early bird rewards. You used to just have to get lucky and be on the site when one became available, but now by using this extension, and by creating an account on http://www.fastbacker.com you can easily get these early bird rewards even after they're gone. The site allows you to subscribe to any Kickstarter project and select the limited reward level you wish to auto-pledge. This project then shows up in the extension project list, and when you click it, it will begin attempting to pledge for that early bird or other limited reward you selected. Over time, it usually is able to get the reward for you. Just make sure you're logged into Kickstarter before starting using Auto-Pledge.
