This software extension, Allow Empty Subject, eliminates the warning dialog that pops up when a message is sent without a subject line. It saves users the trouble of having to manually dismiss the warning each time.
Customization of Thunderbird through CSS and various extensions is quite impressive, but the lack of options for customizing the "no subject" dialog was quite strange. Thankfully, Allow Empty Subject provides a solution to this issue.
To install this extension, follow these steps: right-click the download link and choose "Save Link As..." to save the file to your hard disk. Then, open Add-ons from the Tools menu in Mozilla Thunderbird. Click the Install button and select the downloaded file to complete the installation process.
The latest version of Allow Empty Subject keeps it simple and remains fully compatible with Thunderbird 2. It is important to note that this extension requires a Thunderbird between version 2.0b1 and 2.0.0.* to function properly. Overall, Allow Empty Subject is a useful extension for those who prefer customized options when using Thunderbird.
