very cool thing

Well, it works pretty good

It is not clear how to add a domain to the exceptions? The only input field adds the domain to the "PortAuthority Blocking" list. Had to disable due to the inability to use the extension with a local network application web interface.

Port Authority 2.1.0
Mozilla Firefox 140.0 (64-bit)

This is a very niche issue that I have encountered, if you have a proxmox server deployed and you have this extension in the browser you use to access it you cannot connect to any console sessions within it, you also cannot connect to the server shell. You will receive undefined (code: 1006) as a error with a TASK ERROR: command '/usr/bin/termproxy 5901 --path /nodes/proxmox --perm Sys.Console -- /bin/login -f root' failed: exit code 1. And if you follow that code like I did all you will find is something about a node being offline, which was a bit of an issue for me as I never had a node to begin with.

Does exactly what it says. :)

grate

It's cool but I can't open links from browser to app anymore, nor does it actually add any domains to the whitelist when I try to allow them to bypass.

Doesn't ublock origin do the same with the filter list "Block Outsider Intrusion into LAN" enabled?
