I honestly believe that Firejail is one of the best tools we have in ParrotOS, but it is usually a problem for some applications that cannot run in a sanboxed environment.
The profiles created by the team are quite good, but not perfect, it is up to each user to create profiles that fit their needs, and they must be experienced users. Firejail makes it difficult for non-experienced users to use ParrotOS comfortably, so we are changing security for convenience. I think firejail should be optional, for each user to decide if they want to use it or not. In my case I will continue to use it until we have something better, the profiles fit enough to my needs, and if not I adjust myself, but not all users think in this way.
Or we make using firejail easier for non-experienced users or we give users a choice if they want to use it or not.
