I am a data junkie! I would like to make a homepage that loads when I open FF that has 24 folders or icons. Each folder or icon will have a pull down list of all of the bookmarked websites related to that topic. For example the first folder/icon might be about hydroponic gardening. When I click on it, I see a (long) list of websites related to that topic. Is there an wysiwyg app that I can use to do this? maybe even an add-in? I have searched through ff add-ins but did not find anything - that doesn't mean that it doesn't exist.
