Mailbox Alert is a Thunderbird which allows you to specify, for each seperate mail folder, a message, sound and/or a system command that will be executed when new mail is found there.
This way, you specify different actions for less important folders, or no action at all.
How to Install in Thunderbird:
1. Right-click the link below and choose "Save Link As..." to download and save the file to your hard disk.
2. In Mozilla Thunderbird, open Add-ons from the Tools menu.
3. Click the Install button, and locate/select the file you downloaded and click "OK".
- Fixed a bug where alerts were fired for child folders even if the 'alert for child folders' option was not set (Patch submitted by Jon Siddle, thanks!)
