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.");
