On wunderlist.com we support back to FF16, anything older will trigger the upgrade your browser screen. Our reasoning for this is that the ESR for firefox is currently at FF17. It didn't make sense for us to try support (by support I mean try and get a modern web app to run on it) a version so out of date that even mozilla is not supporting it. It also helps get users out of old version that don't auto-update, or in the case of FF, a version that will never receive security updates.
If you are just looking for the download links for the native apps, you can always go to http://www.6wunderkinder.com/wunderlist which doesn't have the browser restrictions, and update screens that are present in the web app.
