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.
