Attachment Reminder is an Add-On (extension) for Mozilla Thunderbird that scans outgoing email for user-defined keywords (or just use the default list), and prompts you if it looks like you wanted to attach a file but didn't.
New feature: reminder prompt now tells you which keyword triggered the prompt.
Please try it out, test it, and report any bugs found. Any feature suggestions also appreciated!
