The best Gmail Notifier. Period. Thank you for that.

Works great.

First i'd like to say its a great extension. And i know it is not targeted for FF57+ however it does install on FF57b2 however it doesnt work. First it doesnt check for new mails (it says "cant access dead object") and then in th eoptions i cant control watched labels since when i try to unselect inbox it says "observer is null" :)

P.S. on FF55 situation is the same. :(

Ho provato quasi tutti i notifier di email presenti nella sezione Add-On di Firefox e Chrome, ma questo è decisamente il migliore.
Lettura, scrittura ed eliminazione delle email rapida, supporta più di un account contemporaneamente e non si blocca. Consigliato!

C'est un excellent addons. Les lenteurs que j'avais pu constater il y a quelques jours ne sont dues qu'à Gmail qui ralentit ou bloque Firefox pour nous obliger à utiliser Chrome.
Au contraire, en consultant ses mails à l'aide de Checker plus, ça reste relativement fluide, et en tous cas, ça ne bloque pas.
Cet addon serait bienvenu sur Palemoon et sur Brave

There was another review saying it doesn't automatically check for updates in FF 57, so I'm just living a review to say that it does work for me.

I've only been using this plugin a few hours in FF, but I used it for years in Chrome, so very happy to give the 5 star review.

Very useful, best addon for gmail.

Finally, found best gmail checker extension (tested on 55.0.2 64 bit)

ATM, this is the best WebExtensions Gmail checker/button. The built-in popup isn't annoying and if you really want just a button and notifier to Gmail you can just choose so.

By default this is broken in Fx57 though, because Tracking Protection enabled seems to inhibit the addon from logging in. Not sure if this is a Firefox or addon bug.

Checking it now

A lot of reviews are probably from competitors since this is the best one I've used and I've used them all.

Love you
More power

Pues eso, después de instalar este complemento, y teniendo la sesión en Gmail abierta, me pide iniciar sesión en Gmail; y después de hacerlo no ocurre nada, dado que me sigue pidiendo iniciar sesión. He desinstalado el complemento porque además no me convence el tamaño que ocupa...

it looks modern with good features, but it's not what it seams to be.
Auto login always fails.
Manually account is "forgotten" several times, very often asks for login and permission - again and again.
it looks like it does not actualize very often, i have to do it manually.
The configuration is not actualized for FIREFOX users.
Help and config only for Chrome.
simply doesn't do for what it's builded for, at least NOT in Firefox, and it's laggy very often, sometimes fast.
I cannot recommend it anymore after using it 2 Weeks.

After using another much more rudimentary add on, this well written and continually updated add on is a pleasure to use.
Don't feel the need to go into specifics as it's all in the description, suffice it to say if you use Firefox and Gmail this is a must have add on.
