This module is simple, yet excellent. It allows you to select which sites it should act upon and makes it quick to switch to one agent or another. * Perfect for webdevs! * Excellent for Mozilla Firefox Youtube users (I noticed my videos would load immediately when Ipretend to be on Chrome, Firefox is 100% being blacklisted by Google). * Less useful for users who want multiple different user-agents for different websites (most likely, not your case).
