The same way as any other app. Instead of wine *.exe use firejail wine *.exe from console or edit wine app launcher and add firejail prefix. The default wine profile is here: https://github.com/netblue30/firejail/blob/master/etc/wine.profile
@Vincent43 Ahh, ok. Thanks!
@Vincent43 Are there any security/privacy vulnerabilities with utilizing the default wine profile?
The default profile uses blacklists which should block access to common sensitive files but may be not tailored to your specific system if you store important files in various non-standard locations.
To use whitelists you may add:
include /etc/firejail/whitelist-common.inc
whitelist ${HOME}/.wine
whitelist ${HOME}/.local/share/wineprefixes
plus other /home directories you want to access in /etc/firejail/wine.local file (you may need to create it).
It also allows network access, if you don't want it then you may add --net=none option after firejail, i.e. firejail --net=none wine *.exe in launcher/console or add it to wine.local as described above.
