This update upgrades Firefox to version 52.5.1 ESR.
Security Fix(es) :
* A privacy flaw was discovered in Firefox. In Private Browsing mode,
a web worker could write persistent data to IndexedDB, which was not
cleared when exiting and would persist across multiple sessions. A
malicious website could exploit the flaw to bypass private-browsing
protections and uniquely fingerprint visitors. (CVE-2017-7843)
