I have had this happen to me twice in the last two days. It would seem that the firewall rules that I have would not take effect. I would test this by unchecking the rule for firefox, and connections would still be allowed without Blink's firewall asking for it. After a reboot, the rules seem to be working fine.
There is another user on my network who was experiencing a far bigger problem like this. It would seem to happen constantly; even after a blink repair or a reinstallation. Once new rules were created, questions from the firewall would pop up. But eventually new programs that needed the internet would NOT be asked.
I have reported this as a bug to eeye in more detail, but I am wondering if other users are experiencing this? Is this a Blink problem? This problem seemed to have occured right after the newest update, which was about a week or so ago.
