An alternative is to use firejail. If you want temp profiles you can write a script that:
- copies a good initial profile to /dev/shm
- launches Firefox in firejail with —private that points to the dir
- delete the dir
If you want the containers to stick around you can avoid /dev/shm and keep the dirs around instead.
