Quantum will not allow access to my USB drive.
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.
