Mozilla released the fifth maintenance and security release of their popular Firefox web browser. As with all security releases, this one is recommended for all users, and will be downloaded automatically if you already have a previous version installed.

The core of this release is addressing several security issues, of which 3 are deemed critical, 1 high, 1 moderate and 3 low. The critical and high issues are related to: XSS vulnerabilities in SessionStore, XSS and JavaScript privilege escalation, Crashes with evidence of memory corruption, and Cross-domain data theft via script redirect error message.

Other changes include support for the Bengali, Esperanto, Galician, Hindi, and Latvian languages; multiple accessibility fixes; a fix related to multiple signed XPI installations; and more.
