In accordance with these laws, more than sixty Internet regulations have been made by the People's Republic of China (PRC) government, and censorship systems are vigorously implemented by provincial branches of state-owned ISPs, business companies, and organizations.

I'm a devoted Firefox user like most of you. However, at work I use Internet Explorer for couple of web applications that works only on IE. Wouldn't it be nice to embed Internet Explorer inside Firefox as a tab to browse the websites that works only on IE? This is exactly what Firefox add-on IE Tab does as explained below.
This is a great tool for web developers, since you can easily see how your web page displayed in IE with just one click and then switch back to Firefox.
Update: This is Windows specific tool. See how to install IE under Linux using IEs4Linux.
