It supports Firefox 3.0!

Thanks, Chuck Zhao! He has contributed to this version of gtgtl.

Now, it supports springerlink.com and jstor.org.
It also allows users to try redirecting unsupported websites with a warning message.

You can download it at https://addons.mozilla.org/en-US/firefox/addon/6054
Sorry, you may need to login to download it, because it's not publicly released yet.
(It needs to go through firefox addon review process.)
