Hmmm, I've never made a Firefox or Chrome addon, nor do I know how, but if I did, I would try making an addon called Youtube Lite, that changes the DOM of each page and makes it completely functional without JS. It would be amazing to get the horrible comment system working without JS and get rid of the horrible new channel design. You know your site fails when it would actually be *more* convenient and user-friendly to use a plain html version.
