Not wishing, apparently, to be left out of the Patch Tuesday festivities, Mozilla today released the next major version, 21.0, of its Firefox browser for Mac OS X, Windows, and Linux. This version fixes eight security vulnerabilities, three of which Mozilla rates as critical. The new version also incorporates some new features, including:
- Enhanced “Do Not Track” interface
- Support for multiple providers in the Social API
- Suggestions on how to improve application start-up time, if needed
Mozilla also released a new version, 17.0.6, of its Thunderbird E-mail client, for all platforms. The new version provides an update to the Twitter API is uses, and also fixes six security vulnerabilities, three of which Mozilla rates as serious. Further information is available in the Release Notes. You can download installation packages for all languages and platforms.
Because of the security content of these releases, I suggest updating your systems as soon as it’s convenient.
