Rated 5 out of 5 stars

Love this extension! However, now it stopped working with latest thunderbird version. :-(

This review is for a previous version of the add-on (1.68.3). 

Which version of TB are you using? The add-on works fine in TB 68.x. What exactly does not work? Please open an issue at https://github.com/mganss/EmojiAddIn
Thanks
