I can not run Tor Browser by Launcher That present in :Application>Internet>Tor browser. Tor browser opens but says to do restart. but nothing happens. But if i run following command in terminal it works:
"
cd /usr/bin/
./torbrowser-launcher "

i have noticed that in torbrowser.desktop file the value of exec is - torbrowser-launcher %u
when i run it in termainal following outputs happen:

tor browser open and says need restart (same problem from desktop launcher).

My question:

  1. why does this problem occur?
  2. what is firejail and why cant i run tor thorugh firejail’s torbrowser’s profile but /usr/bin/torbrowser-launcher works fine?

Please search before starting a new topic :slight_smile:

Firejail is sandboxing system.
The profile for firejail is /etc/firejail/firefox.profile
