Mozilla Firefox was updated to Firefox 32 fixing security issues and bugs.

Security issues fixed:
MFSA 2014-72 / CVE-2014-1567: Security researcher regenrecht reported, via
TippingPoint's Zero Day Initiative, a use-after-free during text layout when
interacting with the setting of text direction. This results in a
use-after-free which can lead to arbitrary code execution.

MFSA 2014-70 / CVE-2014-1565: Security researcher Holger Fuhrmannek discovered
an out-of-bounds read during the creation of an audio timeline in Web Audio.
This results in a crash and could allow for the reading of random memory
values.

MFSA 2014-69 / CVE-2014-1564: Google security researcher Michal Zalewski
discovered that when a malformated GIF image is rendered in certain
circumstances, memory is not properly initialized before use. The resulting
image then uses this memory during rendering. This could allow for the a script
in web content to access this unitialized memory using the feature.

MFSA 2014-68 / CVE-2014-1563: Security researcher Abhishek Arya (Inferno) of
the Google Chrome Security Team used the Address Sanitizer tool to discover a
use-after-free during cycle collection. This was found in interactions with the
SVG content through the document object model (DOM) with animating SVG content.
This leads to a potentially exploitable crash.

MFSA 2014-67: Mozilla developers and community identified and fixed several
memory safety bugs in the browser engine used in Firefox and other
Mozilla-based products. Some of these bugs showed evidence of memory corruption
under certain circumstances, and we presume that with enough effort at least
some of these could be exploited to run arbitrary code.

Jan de Mooij reported a memory safety problem that affects Firefox ESR 24.7,
ESR 31 and Firefox 31. (CVE-2014-1562)

Christian Holler, Jan de Mooij, Karl Tomlinson, Randell Jesup, Gary Kwong,
Jesse Ruderman, and JW Wang reported memory safety problems and crashes that
affect Firefox ESR 31 and Firefox 31. (CVE-2014-1553)

Gary Kwong, Christian Holler, and David Weir reported memory safety problems
and crashes that affect Firefox 31. (CVE-2014-1554)

Mozilla NSS was updated to 3.16.4:
Notable Changes:
* The following 1024-bit root CA certificate was restored to allow more
time to develop a better transition strategy for affected sites. It was
removed in NSS 3.16.3, but discussion in the mozilla.dev.security.policy
forum led to the decision to keep this root included longer in order to
give website administrators more time to update their web servers.
- CN = GTE CyberTrust Global Root
* In NSS 3.16.3, the 1024-bit "Entrust.net Secure Server Certification
Authority" root CA certificate was removed. In NSS 3.16.4, a 2048-bit
intermediate CA certificate has been included, without explicit trust.
The intention is to mitigate the effects of the previous removal of the
1024-bit Entrust.net root certificate, because many public Internet
sites still use the "USERTrust Legacy Secure Server CA" intermediate
certificate that is signed by the 1024-bit Entrust.net root certificate.
The inclusion of the intermediate certificate is a temporary measure to
allow those sites to function, by allowing them to find a trust path to
another 2048-bit root CA certificate. The temporarily included
intermediate certificate expires November 1, 2015.
