I installed Quantum. I tried to print from Gmail. It denied access to my USB drive. Ubuntu 16.04 sees the drive and accesses it.

I used the security manager in Quantum to allow persistent storage for Gmail. I changed the ownership and file permissions on the /media directory to my user name and It still will not give me access! What do I need to do?

You can check for sandbox security related issues.

You can set this pref to 2 or 1 on the about:config page to lower the sandbox security setting.

  • security.sandbox.content.level = 1
  • close and restart Firefox to make the change effective.

If '1' still doesn't have effect then try '0' to disable the sandbox.

If this didn't work then undo/reverse the change and reset the pref via the right-click context menu to the default value.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

troubleshooting information: 

sandbox:
hasUserNamespaces:  true;
hasPrivilegedUserNamespaces:  true;
hasSeccompBPF:  true;
hasSeccompTSync:  true;
contentSandboxLevel:  3;
canSandboxContent:  true;
