Firefox Extension II

1) I need an existing Firefox extension to be modified with additional functionality like rotating images , responding to mouse clicks, and user input. I need someone who knows Javascript, XUL, CSS, HTML and knows how to make an XPI. The add-on will need to be privately hosted along with an update site. The source is in SVN. More details after selection. Please send examples of [login to view URL] term work possible and very sure to be available. 2) I will also need a IE, Chrome, and Safari extension (toolbar) with the same above functionality; however, this might be a separate project depending on complexity. Thank you for your interest.
