I'm trying to use this browser only for two services, using chrome data saver (the two services are already a compromize of privacy so chrome servers do not take away but give a certain amount of security add) and now trying to find right settings for firejail sanedbox which I installed from the jessie-backports. So no intention of using this to anything else than visiting/using two sites. And yes, the privacy matters in linux are not my best area. I just to use subgraph to secure my self but it was too difficult to mess around cause everything was behind something I didn't understand so here I am. Learning. Chmoding and chowing are things I just now learning not yet knowing exactly what they do. Now I have though learned that they do open many places and that I do not want. Trial and error.

Edit: I don't know yet how to do it but hoping to learn to restrict chromium access only to .cache, .config and some folder where I can stash images for downloading to internet. No need to download from internet anything.

And most probably did not got hacked except by myself messing with the settings from backup.
