Great Addon!
Just a minor minus one star as it can be frustrating on some install.
Actually I've setup my new PC and so Thunderbird. Installed the Plugin and wasn't working at all :-(
At least I had a guess and maybe this may help others as finally it works.
First install was probably while receiving mails and activly showing an E-Mail which has a Label. <- Not working (Also not after restart of TB)
Second try after uninstall the addon. Choosed another Mail folder on startup without selecting any labled E-Mail. Installed Plugin again <- Working :-D
