I have been using thunderbird-78 installed through apt package repository. I was able to run thunderbird in firejail mode using the command firejail --profile=/etc/firejail/thunderbird.profile thunderbird %u.
However I wanted to use thunderbird 91 so I uninstalled apt package and downloaded thunderbird91.tar.gz package file from thunderbird website as per instructions in this post https://askubuntu.com/questions/1367236/update-thunderbird-78-to-91-on-ubuntu-20-04 . I extracted all the files in /home/ajayc/snap/thunderbird folder.
Now I am not able to run thunderbird using the command firejail --profile=/etc/firejail/thunderbird.profile /home/ajayc/snap/thunderbird/thunderbird . The error I get when running the command in terminal is as give here.
