Review for Minimize on Close by David Fleiss
Rated 5 out of 5 stars
Great extension. It does exactly what it promises, it's extremely lightweight. It's functionality ought to be built into Thunderbird as an option, but until it is, an extension like this is necessary (unless you enjoy repeatedly closing the program and having to restart it). Thanks!
