Original GitHub issue: https://github.com/netblue30/firejail/issues/4380

Bug and expected behavior

  • Describe the bug.
    Error: no suitable ./start-tor-browser executable found

  • What did you expect to happen?
    Start Tor Browser using the firejail profile - start-tor-browser.profile

  • What changed calling firejail --noprofile /path/to/program in a terminal?
    Only in this way I can start Tor Browser.

Reproduce
Download file from torbrowser website, I extracted and use
firejail --profile=/etc/firejail/start-tor-browser.profile ./start-tor-browser when I'm in tor-browser directory.

Additional context
Before update 0.9.64.4-1 -> 0.9.66-1 I use the above command
Now I see that profiles for Tor have been changed.
The last profile that implements the assumptions is torbrowser-launcher.profile but it refers to the installed version of browser.

Environment

  • Linux distribution
    Arch Linux
  • Firejail version
    0.9.66

Question
Is it no longer possible to use Tor Browser by downloading it yourself and using firejail along with it?

Checklist

  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • I have performed a short search for similar issues (to avoid opening a duplicate).
  • If it is a AppImage, --profile=PROFILENAME is used to set the right profile.
  • Used LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 PROGRAM to get english error-messages.
  • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • This is not a question. Questions should be asked in https://github.com/netblue30/firejail/discussions.

Download file from torbrowser website, I extracted and use
firejail --profile=/etc/firejail/start-tor-browser.profile ./start-tor-browser when I'm in tor-browser directory.

Where did you extracted it? It must be a one of the ${HOME}/.tor-browser* listed in the profile. Or you need to add a .local and whitelist the path where you extracted it.

firejail --profile=/etc/firejail/start-tor-browser.profile ./start-tor-browser

FYI

  1. Use profile names, it's shorter: firejail --profile=start-tor-browser ./start-tor-browser
  2. If the program and the name match, skip it: firejail ./start-tor-browser

Is it no longer possible to use Tor Browser by downloading it yourself and using firejail along with it?

Still possible. You just need to know how, see https://github.com/netblue30/firejail/wiki/Sandboxing-Binary-Software#tor-browser-home-install or https://github.com/rusty-snake/firejailed-tor-browser.

Before update 0.9.64.4-1 -> 0.9.66-1 I use the above command
Now I see that profiles for Tor have been changed.
The last profile that implements the assumptions is torbrowser-launcher.profile but it refers to the installed version of browser.

You can not install the tor-browser system-wide. torbrowser-launcher is just a wrapper that automates the steps (download, verify, extract to home) to install the tor-browser.

What changed, is that there are no longer three profiles for the same software (which is difficult and risky to maintain). start-tor-browser.profile was a blacklisting profile before 0.9.66, now it is a whitelisting one 🎉.

Before last update I just extract to ${HOME}/tor-browser* - without dot (not hide directory) and everything work fine.

Like you suggest I mv to dot directory, go inside and use:
firejail --profile=start-tor-browser ./start-tor-browser
Still got the same results:
Error: no suitable ./start-tor-browser executable found

I didn't pay attention to this solution, because before last update, I didn't need it.
My solution with long profile (not perfect like you suggest) but it worked as I expected

Now when I use
firejail --private=~/tor-browser* ./start-tor-browser.desktop
it's ok.
But only in this way. Using your first proposal still give the same error.

You can not install the tor-browser system-wide. torbrowser-launcher is just a wrapper that automates the steps (download, verify, extract to home) to install the tor-browser.

Yes I know :) That's what I had "in mind" mentioning the installation.

If it is really in one of

0562ceb658/etc/profile-m-z/start-tor-browser.desktop.profile (L11-L73)

start firejail --ignore=private-bin --profile=start-tor-browser ls -l to see if the file is present and readable.

You can keep this by using locals

start-tor-browser.local:

noblacklist ${HOME}/tor-browser
whitelist ${HOME}/tor-browser

disable-common.local:

blacklist ${HOME}/tor-browser
