When I'm trying to launch Firefox Web Browser through terminal, following message is displayed before firefox is launched.

philossefer@dell:~$ firefoxupdate.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/usr/share/libreoffice/help /usr/share/libreoffice/help none bind,ro 0 0): cannot create directory "/usr/share/libreoffice/help": permission deniedGtk-Message: 11:19:46.906: Failed to load module "canberra-gtk-module"Gtk-Message: 11:19:46.985: Failed to load module "canberra-gtk-module"ATTENTION: default value of option mesa_glthread overridden by environment.ATTENTION: default value of option mesa_glthread overridden by environment.ATTENTION: default value of option mesa_glthread overridden by environment.

Afterwards, whenever I'm trying to launch firefox, after the first launch in-between system boot, following messaged is been displayed before firefox gets launched.

philossefer@dell:~$ firefoxGtk-Message: 11:19:46.906: Failed to load module "canberra-gtk-module"Gtk-Message: 11:19:46.985: Failed to load module "canberra-gtk-module"ATTENTION: default value of option mesa_glthread overridden by environment.ATTENTION: default value of option mesa_glthread overridden by environment.ATTENTION: default value of option mesa_glthread overridden by environment.

I have tried the following solution,by "copy and paste" those messages on google.

What I have tried so far, without any success

Try 1

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

Try 2

sudo apt-get install --reinstall libcanberra-gtk-module

Try 3: Remove firefox and then reinstall

Uninstall:

 sudo snap remove firefox

Reinstall:

sudo apt install firefox

NOTE: I was rebooting the system after, every installation and uninstallation.

reboot

Also Updated my Ubuntu beforehand.

sudo apt update && sudo apt upgrade -y

Current Status: Still those messages are there, when I'm launching firefox using command line.

My question is, why those messages are been displayed and how to get rid of them?

SubQuestion: Is there any difference between launching firefox through icon and through using command line?
