Original GitHub issue: https://github.com/netblue30/firejail/issues/6897

Description

When opening torbrowser-launcher, it will fail to actually open the browser.

Steps to Reproduce

  1. Open torbrowser-launcher, it will either get stuck on 'Installing...' or crash otherwise

Expected behavior

Open

Actual behavior

Crash

Behavior without a profile

Solves the issue

Additional context

Seems to be a missing binary. Doing --ignore="private-bin" solves the issue.

Environment

  • Name/version/arch of the Linux kernel (uname -srm): Linux 6.16.7-200.fc42.x86_64 x86_64
  • Name/version of the Linux distribution (e.g. "Ubuntu 20.04" or "Arch Linux"): Fedora 42
  • Name/version of the relevant program(s)/package(s) (e.g. "firefox 134.0-1,
    mesa 1:24.3.3-2"): 0.3.7
  • Version of Firejail (firejail --version): 0.9.77 20250901 (comes from Tavi)
  • If you use a development version of firejail, also the commit from which it
    was compiled (git rev-parse HEAD):

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
    • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

It's an incompatibility with uutils. Closing.

Edit: seems to have to do with ln.
