This update upgrades Firefox to version 52.6.0 ESR.

Security Fix(es):

* Multiple flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. (CVE-2018-5089, CVE-2018-5091, CVE-2018-5095,
CVE-2018-5096, CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5102,
CVE-2018-5103, CVE-2018-5104, CVE-2018-5117)

* To mitigate timing-based side-channel attacks similar to "Spectre" and
"Meltdown", the resolution of performance.now() has been reduced from 5s
to 20s.
