I have an issue launching firefox with the above error message. When I tried some of the solutions posted in this forum I receive the error message

user is not in the sudoers file. This incident will be reported

How do I launch firefox without requiring any profiles ? I mean its just a freaking internet browser and I need it for my exam. Help me please.

firefox -ProfileManager
firefox -P

Returns

Your Firefox profile cannot be loaded. It may be missing or inaccessible

  1. Usually I fix this by restoring correct rights on corresponding catalogs with:

    sudo chown $USER: -R ~/.cache/mozilla/ ~/.mozilla/firefox/

    1. Kill all currently running process

      killall firefox
killall thunderbird

    2. Remove the cache Files

      Note: Backup them before removing.

      rm -rf ~/.mozilla/
rm -rf ~/.cache/mozilla/

      Try running Firefox now: $ firefox

      If it still doesn't work then proceed further.

    3. Change the ownership of the following folders

      sudo chown -R $USER ~/.cache/.mozilla/
sudo chown -R $USER ~/.mozilla/

      If the above step is NOT successful, then try the following

      sudo chown -R $USER:$USER ~/.cache/.mozilla/
sudo chown -R $USER:$USER ~/.mozilla/

      If the above step is NOT successful, then try following

      sudo chmod -R 777 ~/.cache/.mozilla/
sudo chmod -R 777 ~/.mozilla/

    4. If all the above steps NOT successful, Then change entire cache folder permission

      sudo chown -R $USER ~/.cache
sudo chown -R $USER:$USER ~/.cache
sudo chmod -R 777 ~/.cache/
