Original GitHub issue: https://github.com/netblue30/firejail/issues/1716

I'm using
firejail --private-home=.mozilla firefox %u --no-remote
for Firefox. So that my firefox profile, history etc. is not changed but my settings are used.

How to achieve making an directory accessible outside this sandbox like ~/Downloads?
Currently this folder is empty and I it not possible to exchange files with the sandbox.
They are lost on terminating the process because the temporary filesystem is deleted.

I know about firejail {--ls | --get | --put} but is there a more conveniet way to share a directory?

If you are the only one using the computer, you can create a directory outside your home and configure Firefox to use it as Downloads:

$ sudo mkdir /tmp-downloads
$ sudo chown username:username /tmp-downloads

The only thing in Firejail blacklisting files outside the regular Unix file system hierarchy is --apparmor option.

@damadmai I actually used to use private-home before but found it tedious for exactly this reason. Nowadays, my regular profile does whatever it does (I have many privacy addons), but I also wrote up a little script to create a temporary firefox profile and copy over specific files/folders (see #2031 for the motivation I had for writing this script). The latest version of the script can be found at firefox.common (you can disable the private-lib stuff if you so wish, but imo it adds a bit of additional security and should just work OOTB). Note that the private-lib parts require gen_libraries. If you decide to use the script, please open an issue in that repository if you have problems.
