'China Channel Toolbar':
See what it's like to be a Chinese internet user. This FireFox add-on forwards your IP address through a proxy server that is behind China's censorship: The Chinese Government literally sees your web browsing as taking place on a computer in China, and filters your traffic accordingly. If you go to a site they don't approve of, your internet connection will be blocked for 15 minutes. Fortunately, you can quickly and easily go back to your normal way of browsing to continue what you were doing.

PermaTabs sets any web site of your choice as a permanent tab so you will not close it by accident, with the tab launching automatically when you start Firefox. A
simple key command (Alt+P) toggles the tab as 'PermaTab' or not.
