Backported profiles

If you want to use a stable firejail version rather then the latest git, you must use profiles with no features added in later versions.

Using stable-profiles

Call ./install.sh with --firejail=VERSION, e.g.

$ ./install.sh --firejail=0.9.60 ~/Downloads/tor-browser-linux64-8.5.4_en-US.tar.xz

or, if you use the manual install, download the profile and the .desktop file for your firejail version instead of the files from the repo-root.

For other special aspects, see the README of the respective version.
