Your home page doesn't have to be on the internet. It can be an HTML file on your own computer. So why not experiment with creating a one-page (local) 'website', using something like, Serif WebPlus Starter Edition, which can have all of your favourite links on it?
That page can be stored anywhere you like on your PC. Open it in Firefox, then go to Tools > Options > General (tab). Under 'Startup' click 'Use current pages', and then on 'OK'
