I love the style and the way it goes with the new firefox design

Works great, (doesn't work with private browsing)

best

goooooooooooooooooooooooooooooooooood

I'm so disappointed... It doesn't work with Firefox Quantum at all.

Hi, Jason! You wrote "Works for me, use the default settings." But I can't find reset button. Where is it?

DOES NOT WORK with quantum. Takes you to a link to "refresh Firefox" which will REMOVE EVERYTHING from FF: settings, bookmarks, etc.... Tried this in chrome and had similar problems. STAY AWAY!

I really hate the material design.

Works better than other extension. UI is much more elegant too. Exactly what I am looking for. Thanks for making this.

Good

This makes my life so much easier. I had it for Google Chrome and I switched to Firefox today. I immediately installed this and the addon is stuck on "Loading settings...." Is this not updated for Quantum? :(

EDIT: Thank you! It's working as intended. <3

Gmail window is too big. I want resize it as in Chrome (compact).

Funziona benissimo!

I love this extension but this just refuses to work on Firefox. Works great on Chrome.

All the help materials by this author are for Chrome.

Excellent replacement for Gmail™ Notifier (restartless).

Love this extension on Chrome, really pleased it's available for Firefox. Really miss being able to delete messages from the pop up notification and it's a little slow to respond but I wouldn't use any other mail checker.

Works perfectly and far cleaner than other similar add-ons. Essential download.

Voice reading is not supported on Firefox? I don`t see any option about voice language.. Loved it in Chrome.

O melhor ate agora.

the best

THE best gmail extension to ever exist. Developer is also top notch and extremely up front. I remember reading a while back about how someone had managed to push a malicious update and you handled it like a pro. Very happy to see this on FF!

Best in it's class. Lots of well thought out options so you configure exactly the way you want. Developer extremely responsive - issues resolved quickly. This isn't one of those extensions that rest on it's laurels and before you know it are showing their age. The entire Checker Plus series of addons are consistently evolving - the developer is always thinking about ways to improve them. The Checker Plus extensions were originally developed for the Chrome browser where they have been very popular for years. This developer took the time and effort to port his extensions early on in the Fx web-extension process. He didn't wait for Fx 57. Highly recommended.
