Hi, I've released an update (version 3.23, exactly I've uploaded the new update on 2nd November – 7 days ago– as you can see on the website https://www.emojiaddon.com/news/ or on GitHub).
But the delay on publishing is due to Mozilla because of the add-on is "Firefox Recommended" and the revision process is longer (it has to be checked manually from a developer).

I'm so sorry about the inconvenience, when the update will be published, you'll find all emojis until the latest version (Unicode Emoji standard v15.1). Please, wait the new update.

I remain at your disposal: contact me via Telegram or email!

I hope you'll like it and, in case, please remember to update the review 😇

**Update: Mozilla has approved the update and now you can install the 3.23 version of Emoji. Hope you'll like it!

Thank you very much
