It used to work well. Now that it's been "updated" to automatically detect logins, it no longer supports Outlook/Hotmail. If I log off and back on, it's there briefly, but then disappears and won't return.

No longer recognises e-mails. Google, Outlook and others do not work.

Pros: It can handle Multiple Google Accounts well. (Previously X-notifier(not Neo) needs re-login to the other Google account.)
Cons: It can not keep accounts information. (Previously X-notifier(not Neo) can keep them.) Accounts information on the dashboard and the right click menu of the icon disappear automatically every time. I guess this is a side effect of Neo's automatic login detection. So, I still need to use X-Notifier(not Neo) to keep my account settings.
Conclusion: Neo has not yet been able to become a successor to X-Notifier.

Hace ya un tiempo que lo uso, manejando cuentas de hotmail y gmail. Me parece ligero y útil; como siempre gracias por los complementos útiles.

No tiene opción para Yandex Mail.

No me reconoce el email aol.com. Tanto para gmail con varias cuentas, y yahoo de lujo.

comprehensive functionality
very fast support

It works many times better than X-notifier.

It does not reset after opening Gmail, and deleting mails....no options other then check interval????

Le quitaron muchas opciones del X-notifier que lo hacían bueno

Better than X-notifier

i liked this addon very much. it's been working so well. thank you.
the recent update 84.0.2 has broken this addon. i see that the new update version 2.2.8 has just been released. but instead of showing unread primary message count, it shows all unread email count. i hope it will get fixed. thanks.

Would be nice if containers would be supported (Google Container addon)
