    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 20.04 LTS
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    USN-4546-1 caused some minor regressions in Firefox.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    USN-4546-1 fixed vulnerabilities in Firefox. The update introduced various
    minor regressions. This update fixes the problem.
    
    We apologize for the inconvenience.
    
    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, conduct cross-site
     scripting (XSS) attacks, spoof the site displayed in the download dialog,
     or execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 20.04 LTS:
      firefox                         81.0.2+build1-0ubuntu0.20.04.1
    
    Ubuntu 18.04 LTS:
      firefox                         81.0.2+build1-0ubuntu0.18.04.1
    
    Ubuntu 16.04 LTS:
      firefox                         81.0.2+build1-0ubuntu0.16.04.1
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
