    Original advisory details:
    
     Multiple security issues were discovered in Firefox. If a user were
     tricked in to opening a specially crafted website, an attacker could
     potentially exploit these to cause a denial of service, spoof the prompt

    execute
     arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:

      firefox                         82.0+build2-0ubuntu0.16.04.5
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
