Move Player Plugin?

So I have a question about the Move player plugin that is used to watch streaming video on the CW and ABC's new video sites. I can't get it to install on Portable. I have been able to get it to work on my home installation of Firefox, and I tried copying everything from the plugins folder, but it still doesn't work.
Has anyone gotten this to work on portable Firefox? If so, what do I do, and if not, can anyone help me figure out what other files AI might need to manually transfer?
Thanks!
