Blocking cupsd in firewall stops Vivaldi from viewing webpages

  • I have my firewall set to interactive mode so that it alerts me to any traffic pattern that doesn't have an explicit rule. Mostly because of MS Office. Anyway I noticed /usr/sbin/cupsd was requesting internet access at odd times so as a test I blocked it entirely. Lo and Behold I can no longer use Vivaldi. I get "page unavailable" messages for every single page. Removing the rule resolves the issue entirely. Logs show that cupsd is trying to access whichever IP address I was browsing to in Vivaldi.

    I can find no printer settings (or flags) in Vivaldi that could account for this behavior. Google searches turn up nothing. MacOS Sierra 10.12.6 and Vivaldi 1.11.917.39 (Stable channel) (64-bit).

    So my question is: why in the world does it seem that Vivaldi is going through cupsd to access the internet and how do I go about troubleshooting why this might be occurring?

  • Ok so I found the issue. My firewall was falsely reporting which app was requesting the access to the internet. cupsd has nothing to do with Vivaldi as far as I can see.

    Be careful of the ESET firewall people. Frequent restarts are apparently necessary to avoid this erratic behavior when using Interactive mode.
