Mozilla Thunderbird is a free, open-source, cross-platform application for managing email and news feeds. It is a local (rather than a web-based) email application that is powerful yet easy-to-use. Thunderbird replicates the new look and feel of Mozilla Firefox in an effort to provide a similar user experience across all Mozilla software desktop or mobile and all platforms. Changes:
• Fixed attachments sometimes could not be removed from the composition window using the keyboard.
• Numerous security fixes. Download: Mozilla Thunderbird 17.0.3
