OS X Firewall Block all incoming Connections Affecting Software Updates?

I just bought a 2017 Macbook Pro with the latest OS (Mojave). In the OS X Mojave Security and Privacy-Firewall settings, I set Firewall to “Block all incoming connections” as I am extra cautious, but will my software (such as Chrome web browser, Firefox, etc.) still get new updates? For example, will my Firefox browser still get the latest software updates or will I have to manually check for software updates because the firewall is blocking all incoming connections?
