User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0 Build ID: 20120423122928 Steps to reproduce: 1) I defined a new default style for message composition including a specific font (Arial) and color (dark blue): Preferences -> Composition -> General -> HTML Preferences -> Composition -> General -> HTML -> Send Options -> Send the message in HTML anyway 2) Selected preference for sending HTML messages: Account Settings -> Composition & Addressing -> Compose messages in HTML format 3) Composed & sent an email message Actual results: Message compose window appears to create the message using the desired style. As I'm typing the characters are displayed using selected font & color. But, the message that is actually sent does not keep that style. Recipients receive message without selected formatting applied. Expected results: Recipients should have received HTML formatted message using the selected default composition style.
