Firejail: Allow folder from USB device mounted in /mnt/

[Philippe734]

I’m using Firejail with Firefox in Ubuntu 18.04 LTS. I need to allow a specific folder in Firejail to set the Downloads folder in Firefox. The folder is on an USB device, mounted at /mnt/stuff/. How to set up Firejail, in order to select the folder /mnt/stuff/ in Firefox (for Downloads)? I tried to add whitelist /mnt/stuff in the file /etc/firejail/whitelist-common.inc but it’s not working, Firefox can’t access to that folder.

Hi @Philippe734, with whitelist /mnt/stuff you're already halfway there.
In addition put ignore disable-mnt into /etc/firejail/firefox.local, that should get it running.

@GeoffK59
if it is directly attached to your computer see https://github.com/netblue30/firejail/issues/1925#issuecomment-386812752

if it is connected to your router see #1560
