[Sage] can't download Sage

[Chris Sitka]

I can't get Sage to download from the home page. 
http://sage.mozdev.org/install/
It just won't work.
I have gone to Mozilla home searching for it and can't find it there.
Even though Sage home page claims to have won a competition there.
It has been recommended to me as a RSS feed extension to Firefox.
How can I get it downloaded to my computer.
Please help.
