Thanks for your response, I would also choose anywhere instead of an own script, but I won't include Twitter into my website. I am trying to integrate the Twitter support into my Firefox Addon, but I don't know how I have to do this. I think that I can't integrate the Twitter anywhere script into my plugin. The security problem wouldn't be so big, because the API key would be hidden in the FF plugin. Is there any solution for my "special" problem, or exist there already anything for Firefox plugins?
