Updated firefox packages fix security vulnerabilities

A use-after-free flaw was found in the TLS 1.2 implementation in the NSS library when client authentication was used. A malicious client could use this flaw to cause an application compiled against NSS to crash or, potentially, execute arbitrary code with the permission of the user running the application (CVE-2017-7805). 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-2017-7810, CVE-2017-7793, CVE-2017-7818, CVE-2017-7819, CVE-2017-7824, CVE-2017-7814, CVE-2017-7823).
