What would be the best way for me to sync multiple folders in various locations across Windows 7, XP, Ubuntu, OSX computers as well as firefox addons (that might just be a folder anyway, i'm not sure)? Online backup would also be appreciated, as would a friendly and pretty interface (I love Dropbox it's just not up to everything I want).

For Firefox and addons alone, try the FEBE extension.
