On a Cinnamon Mint 18.1 here, I don't have the problem you mention when I run "firejail --overlay firefox".

/run/user/1000/dconf is the configuration directory for GTK. As soon as Cinnamon starts, the directory should be created. I wouldn't worry too much about it. It has no impact on your browsing, security, or anything else.

@xdpFrank:

Do you still have this problem?
I know I've had issues before with disabling noroot in the firefox profile (as well as a bunch of others). Since overlay disables noroot, that might be causing this problem (if you still have it).

@chiraag-nataraj commented on GitHub (May 3, 2018): @xdpFrank: 1. Do you still have this problem? 2. I know I've had issues before with disabling `noroot` in the firefox profile (as well as a bunch of others). Since `overlay` disables `noroot`, that might be causing this problem (if you still have it).
