Hello, Once Firefox adds "addons synchronization", I will add it also for Android: https://bugzilla.mozilla.org/show_bug.cgi?id=1625257
As a workaround, I've discovered a page where you can write a note and then send it using Firefox built-in "Send tab to device" feature, even from or to Android: https://temporarynote.com/ (since the note you write is embedded into URL, so sharing the link shares the note)
