Mozilla Releases Firefox 47 and Firefox ESR 45.2

In early June Mozilla released their scheduled security updates for Firefox and Firefox ESR (Extended Support Release) raising their version numbers to 47 and 45.2 respectively.

Firefox 47 resolves 17 security issues more formally known as CVEs (defined). Individually the severity of these issues are as follows:

====================
3x critical severity CVEs
5x high severity CVEs
4x moderate severity CVEs (includes 1x CVE that addresses 4 issues, making 7x issues in total)
2x low severity CVEs
====================

Firefox ESR 45.2 resolves 9 security issues:
====================
3x critical severity CVEs (2 of these CVEs address multiple issues, exact number is unknown)
5x high severity CVEs
1x moderate severity CVE
====================

As always full details of the security issues resolved by these updates are available in the following links:

Firefox 47
Firefox ESR 45.2

Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, please update it as soon as possible to resolve these security issues.

In general, Mozilla Firefox updates install without any issues, however as always I would recommend backing up the data on any critical device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.
