Greatest add-on! I too cannot live without this. I often downgrade TB for this app to work. Quicktext became main reason to use TB. In the past, not enough updates and frustrated me. Hope it keeps updating in the future.

This review is for a previous version of the add-on (2.9).

Just click on "check for updates" at the little gear button in the Thunderbird Add-On Manger.
