   In a terminal window:   
      
   $ cat /etc/mtab | grep firefox      # The snap mounts are in /etc/mtab   
      
   /dev/loop6  /snap/firefox/1810  squashfs ...   # Snap modules are loopback   
   mounted   
                                                   # Snap contains everything   
   Firefox needs   
                                                   # But the file system access   
   is "contained"   
   *******   
   $ snap list   
      
   Name     Version     Rev   
   firefox  104.0.2-1   1810   
      
   *******   
      
   $ which firefox   
      
   /snap/bin/firefox              # snap presumably, is ahead of /usr/bin in the   
   PATH variable.   
      
   *******   
      
   # Now, run it, check for error messages into the Terminal window   
      
   $ firefox   
      
   *******   
      
   Then tell us, what the firefox command returned, that is abnormal.   
      
   You can see in my example, there is a shedload of messages. VAAPI   
   would be on an Intel graphics system, whereas my card is NVidia.   
   The viaduct error is spit out, during the Firefox shutdown sequence.

   That's a pretty normal looking output, indicating   
   nothing is wrong :-) The output would be a lot quieter   
   on a failure.
