Original GitHub issue: https://github.com/netblue30/firejail/issues/395

I suggest to tighten the existing Thunderbird profile. The following settings work for me:

# Firejail profile for Mozilla Thunderbird (Icedove in Debian)
noblacklist ~/.thunderbird
noblacklist ~/.gnupg
noblacklist ~/.mozilla
mkdir ~/.thunderbird
whitelist ~/.thunderbird
mkdir ~/.gnupg
whitelist ~/.gnupg
mkdir ~/.cache
mkdir ~/.cache/thunderbird
whitelist ~/.cache/thunderbird
whitelist ${DOWNLOADS}
read-only ~/.mozilla
include /etc/firejail/disable-mgmt.inc
include /etc/firejail/disable-devel.inc
include /etc/firejail/disable-secret.inc
include /etc/firejail/disable-common.inc
include /etc/firejail/disable-terminals.inc

caps.drop all
seccomp
protocol unix,inet,inet6
netfilter
noroot
tracelog
shell none
include /etc/firejail/whitelist-common.inc

Making ~/.mozilla read-only is required as otherwise clicking URLs in Thunderbird do not open in Firefox. I haven't tried with other browsers. The included files need to be adjusted to the newly introduced structure
