    Multiple security issues have been found in the Mozilla Firefox web
    browser, which could potentially result in the execution of arbitrary
    code, cross-site scripting or spoofing the origin of a download.
    
    Debian follows the extended support releases (ESR) of Firefox. Support
    for the 68.x series has ended, so starting with this update we're now
    following the 78.x releases.
    
    Between 68.x and 78.x, Firefox has seen a number of feature updates.
    For more information please refer to
    https://www.mozilla.org/en-US/firefox/78.0esr/releasenotes/
    
    For Debian 9 stretch, these problems have been fixed in version
    78.3.0esr-1~deb9u1.
    
    We recommend that you upgrade your firefox-esr packages.
