what i use: *.facebook.com:443

note that this may cause delays with whatsapp in sending/receiving messages. it also sometimes delays placing/receiving calls. you can temporarily disable noRootFirewall for critical times. I don't know how whatsapp uses the facebook domain. It clearly needs the facebook domain to work optimally, but it is not critical.

Last year parts of fbs service went down. What's interesting is that WhatsApp, Instagram and Fb all broke in the same way in that people were unable to send or receive photos.
