Works in Privacy Mode! Yay! Rated 5 out of 5 stars

I was looking for a plugin that would give me a pop up when an email arrived. My issue was I always work in Privacy/Incognito mode. This is the only one that works. Fantastic. Thank you for your work.

Black text on dark grey background Rated 1 out of 5 stars

I have always a black text on dark grey background and can not read the EMail if it isn't in HTML.

Imprescindible Rated 5 out of 5 stars

Para las personas que trabajamos con varias cuentas de gmail, este tipo de complementos se hacen imprescindibles. Gracias a los desarrolladores, porque realmente funciona y hace bien su función. El único problema que le veo es que no trabaja con más de 3 cuentas a la vez. Por lo demás, perfecta.

La única extensión que funciona realmente bien Rated 4 out of 5 stars

A veces las opciones más sencillas (y más ligeras) son las mejores... Solo necesita un pequeño rediseño, por lo demás cumple con las expectativas.

Not fully functional Rated 2 out of 5 stars

Despite what it says in the very badly written FAQ, this extension cannot show notifications for only your "primary" category. It either shows notifications for everything in inbox, or nothing. No tinkering with the option "feed" section will change that. X-notifier could do that without a problem but this can't.

Caído el Gmail Checker, me parece el mejor reemplazo Rated 5 out of 5 stars

No es fácil luego del hábito con el Gmail Checker tantos años, pero este me parece un muy buen add on, nada intrusivo en la pantalla, con razonable -tal vez de más- detalle de los correos, y razonable facilidad para manejo de cuentas. Gracias !!!

Good, but has an annoying flaw Rated 3 out of 5 stars

For the past several versions I've had to hit the Trash icon twice before it will delete an email. It used to be instant on the first click, but if I don't hit it twice then I have to wait around 10 seconds before it will go to the next one. Even hitting it twice still takes a couple seconds now.

Gmailデスクトップ通知 Rated 5 out of 5 stars

Firefox 53.0.3 32bitを使っている者です。
Gmailの通知機能を使いたいと思い、設定からデスクトップ通知へ。
このアドオンを使わなくても通知は来ますが常にGmailをブラウザで開いたままにしないといけません。
ですがこのアドオンをインストールしたら、ブラウザに開いたままにしなくてもメール通知が来るようになりました。
他のGmailアドオンは使ったことありませんが良いと思います。

Why do I need to sign in every time I open FF? Rated 2 out of 5 stars

It's a good app, but when I start FF I want it to log into my account and for it to start working, not sit there and wait for me to log in.

It does exactly what I want Rated 5 out of 5 stars

It does exactly what I want. And the great thing is that, it shows you weather you have new messages on the icon and you don't have to go to Gmail.

Fine! Rated 5 out of 5 stars

works beautiful
