Not working on Livemocha.com

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to a page with kanji on Livemocha.com (example: 
http://www.livemocha.com/flashcard_sets/view/1533401 or 
http://www.livemocha.com/submissions/review/16665003?tok=sub )
2. Press the Furigana Injector button.
3. Nothing happens.

What is the expected output? What do you see instead?
I expect to see the furigana added after (or above when I have Ruby on) the 
kanji, but nothing happens.  It works on other websites.

Which browser are you using, Firefox or Chrome? On what operating system?
Firefox  3.6.12, Windows 7 64 bit

Small update:
I just discovered you can right click and tell it to inject that way.  It works 
after that on the flashcard page, but not all the time on the submission page, 
and more often in some areas than others.  The review area works more than the 
submission area.

Some people also report it does not work on youtube or facebook too.
