Multiple security issues have been found in the Mozilla Firefox web
browser, which could result in the execution of arbitrary code,
privilege escalation or information disclosure.

For the stable distribution (stretch), these problems have been fixed in

We recommend that you upgrade your firefox-esr packages.
