You can change the bitdefender settings if you own an Paid version. I have kept mine to auto update at 12hour interval but I update it when I'm sitting idle (default setting on BD is 1hr if I remember correctly). FF doesn't update often. They release an update once every 15 or 30 days (just an example), while the addons depend on the developers.
In short its not an issue if you've security related softwares updating regularly its good for your system.
