Holy Moly this severely screwed up my Mint 20.2. It seems maybe the default profiles are incorrect for this version of Mint.
It corrupted a number of my software programs. I am running Linux Mint 19.1 and it destroyed Thunderbird, LibreOffice (all packages), Firefox and the computers it was loaded on were really screwed up. I about lost my mind trying to figure out what had caused the computers to be so messed up. Finally I uninstalle Firejail and the computers were all fine after that.
It totally killed my Linux Mint Cinnamon 18.3 I had to rebuild my system. NOT recommanded.
Highly recommended. Essential for anyone wanting to enhance online security.
A must have for those who are intended to try experimental features and third party softwares.
Great simple piece of software adding an extra layer of security.
