Whilst I don’t have any issues, not using it and had to look it up.
Synergy is an app that shares one mouse and one keyboard across multiple computers and monitors. Instant download, easy to setup in minutes.
I suspect you might be getting an issue with the Network Inspector rather than the Firewall. Relating to a previous bug (my interpretation).
See these images of my settings and see if adjusting yours helps. Don’t try unchecking them all at one try one at a time to find the true culprit. My settings derived from getting hacked off by the frequency Network Inspector after an update to 25.2.xxxx. Note a new program version has just been released 25.3.xxxx, check that out first and see if this bug was squashed.
