Restrix Proxy Toolbar allows you to unlock websites directly from your browser without even entering to Restrix webpage.
It provides an orange search field where you directly type the blocked address and the toolbar will display it for you. Apart from that, the toolbar allows you to search for anything in the web, even specifying your search (toolbar components, images, videos,etc.), just by entering keywords in the search field. It also includes an email notifier, weather forecaster, an online radio player, and a list of helpful links, including games, proxies, files sharing and uploading, to name but a few. There are other buttons on the toolbar that seem not to be working; you should eliminate them from the options menu, so the toolbar looks less crowded and organized without things that you don't use. From that menu, you can also add other useful components like pop-up blocker, Facebook log-in link, and even customize other aspects of the toolbar.
In short, Restrix Proxy Toolbar is a wonderful tool to unblock sites, including other useful links and buttons that make the toolbar worthwhile.
