Firejail A Namespace Separation Security Sandbox
There are certain files required in order for Firejail to work properly. Get them first and if already having them skip it.
You will find it in your menu. There will be two options. One will be setup and other will be the direct launcher.I will advise you to use setup version as I found it easy and detailed. Also, it will allow you to use your installed applications easily and offers navigation.
I would love to have it on my system and will also advise you guys to try it out. I will also love to hear your comments on the applications. Make sure to drop a comment below.
