Thank yoy, it's greatest checker.

До обновления было ЛУЧШЕЕ дополнение! После обновления - стало хуже некуда!
В течение получаса ЗАБЫВАЕТ все ящики и пароли к ним! Надо каждый раз вводить всё заново! Отстой!
Автор, Верните предыдущую версию!

Worked at first, but now it never remembers multiple accounts, only recognises two of my three accounts, and opens one of my accounts as another account. Tried all the fixes suggested in troubleshooting and none work, problem is persistent. Very frustrating.

Es imprescindible para mí.

i have this for chrome but is there a version of this for yahoo once 57 is out

Just switched from Chrome and, after changing the button to open gmail in a new tab via the options, this works the same way as the extension I was used to using before.

no longer working with nightly 58 check the issue please

thank, works great

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.
