Web site updated today. Private-etc firejail option is not compatible with Ubuntu 25 - you won't be able to connect to the inet.

@Victor M chatGPT mentioned an app to me yesterday, FlatSeal, might have some relevance for Ubuntu hardening?? I haven't installed it yet...

Yes FlatSeal is useful if you use Flatpaks. FlatSeal can let you minimize the connections between the flatpak and the outside world. You can freely experiment/disable what you see listed because there is a 'reset' button for when things don't work out.

Yes I installed Flatseal, and made some permission tweaks for one flatpak, so far
