Thank you, I will fix that.

The code should be viewable. I think you can open it like a zip.

Well, I did it using the Addon-SDK, which is recommended for various 
reasons. I will see how it develops in future.

I am not sure, whether it works anymore. Somehow the button turns black, 
which could be a general problem with Flashproxy though. No Firefox 
support? Maybe use another library? I wonder whether socket.io or sockjs 
could be used, since they allow fallbacks. Would be really interesting.

Oh? I thought cookies were domainwide. I will have a look on it.

I noticed this too. Cool, now I know how to fix it.

Maybe related to the SDK. I will have a look on it, once I have more time.

Thanks so much for testing and providing feedback! :)
