Rated 3 out of 5 stars
Thunderbird did a dirty trick when my profile was damaged and auto updated itself. Now I find most of my addons don't work, and this is one of them. I've used it for about 7 years or so and found it very useful. The ability to have custom alerts for different accounts and folders (useful when using server side filters) and the ability to silence the alert for routine mail such as newsletters etc was invaluable. I hope it can be updated or a replacement arrives soon.
The star review is simply because it doesn't work (can't give it full marks when it doesn't work!), otherwise, it would get full marks.

I've used this for a year or two and find it very useful. The latest version adds a few useful options.
I am puzzled that for some folders, when testing the alert, I get the following message even though the alert works
"XX] error at undefined:617: [Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsILocalFile.leafName]" nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)" location: "JS frame :: chrome://mailboxalert/content/mailboxalert_funcs.js :: <TOP_LEVEL> :: line 617" data: no]"
Also sometimes, the custom sound is cut off half way through. Don't know if that is a system thing or its within Mailbox.
