Doesn't seem to do much alone. Firejail and tools seem to rely on bwrap and flatpak but it worked through it. You run the first time ./sandboxed-tor-browser --install and then you can run ./sandboxed-tor-browser --advanced config to configure it. Although I can only trust it is somehow sandboxed because from your browser you may only have access to the directories you specify in config, but it is hard to tell how sandboxed it really is. It seems as a good direction for experimentation.
I am sure the future is heading that direction
PS Can on use a disk based tor as a proxy for the sandboxed tor, and does this make any sense?
