Stopped working as of January 5, 2018. Found the issue - there is an explicit date check in the addon bootstrap code that disables it on that date (based on arcane addon "build" version).

To fix this issue:
1. Download addon .xpi file (google for instructions)
2. unzip .xpi file (xpi is simply a zip archive)
3. locate file bootstrap.js in the archive, open in text editor
4. look for the code like this:
compile:function(){
if((build+'').length != 10) Services.prompt.alert(null, 'CompileAddon', 'An error occured');
if(new Date().getTime() > ((build+'').length == 10 ? build*1000 : build)+(3*30*24*60*60*1000)) return false;
return true;
}
5. Comment out or delete line that begins with "if(new Date().getTime..."
6. Zip the archive back (make sure to zip from inside the xpi directory, so that there is no additional path to files). Rename resulting zip file into something.xpi
7. Manually install the new addon file into Thunderbird

To the developer - this sort of bogus stuff gives a bad name to software developers.
