Malheureusement, depuis quelques jours ça ne fonctionne plus. j'espère une mise à jour rapide, car cette application est vraiment pratique et très utile.

26 May 2017 - No Longer Working Rated 5 out of 5 stars

I opened a new Gmail account a couple of weeks ago, but was never able to get it to work with GMail Checker.
Today GMail Checker is not working at all, for my old accounts.
I truly hope this can be fixed.
Life is SO much easier with this great add-on.

Broken as of 5/26 Rated 5 out of 5 stars

I love this extension and I'm really hoping it gets updated - unfortunately whatever changes google has been making to their login process lately has broken this! There's really no other extension that does what this one does as well as it does it, so here's hoping there's an update soon!

Google broke this add-on !! Rated 5 out of 5 stars

Was working but now won't remember accounts. Please fix if possible as it my favourite add-on. So simple :-)

Old, but works very well... Rated 5 out of 5 stars

I guess I'm a Gmail Manager orphan (waited and waited for bug-fixes that never came), but I should've used this add-on from the start.

Working flawlessly on my Windows 10 box, running FF 49.0.1. Simply to set up, doesn't cause any issues when Google change Gmail. Great stuff.

Smart, Fast, Works Perfectly, So Convenient Rated 5 out of 5 stars

For Firefox 48.0.2, GMail Checker works very well. Installation is fast and easy. Its drop down list shows the email subjects, or choices to customize. You need to allow less secure apps to log into your Google Mail for this add-on to work, but it will tell you and provide the link. The icon changes color and counts mail. I contributed to the creator of this add-on. I like it a lot.

no support for gmail based account? Rated 3 out of 5 stars

I use Gmail Checker 2.6.6. Why in this extension does not work support for gmail based account.
Can I expect that soon it will be fixed?


Notification Is Barely Seen - Needs Upgraded Rated 5 out of 5 stars

I test it and now I fully use your "GMail Checker" addon, because is the best, honestly!
Still....why don't you make an upgrade to this addon for the notification to be MORE visible, because now we can barely see it! It's to tiny and so small!
Make the "email received number" caracter to be bold and bigger, or/and make the envelope icon to turn into full red colour (or other colour) and to flash until we check our emails, etc.!
Please do something about it and don't leave it like that!
Thank you!

Great addon but... Rated 3 out of 5 stars

For some reason Gmail doesn't seem to like this extension. I keep getting "Sign-in attempt prevented" messages from google. The email says
"Someone just tried to sign in to your Google Account xxx@gmail.com from an app that doesn't meet modern security standards.

"We strongly recommend that you use a secure app, like Gmail, to access your account. All apps made by Google meet these security standards. Using a less secure app, on the other hand, could leave your account vulnerable. Learn more.

"Google stopped this sign-in attempt, but you should review your recently used devices:"

Interesting though, google's attempts to stop the sign-in fail because I am, and the app is signed in. Goodle occasionally kicks me off and sends me to a page to sign in again.

I suspect google just wants us to use all google stuff but the problem is, they have nothing to replace this-- at least for firefox. Curious, other similar addons I've used don't have this problem.

Massive slowdowns Rated 3 out of 5 stars

An invaluable extension that is now causing massive slowdowns in the latest firefox for me. my boot times on the browser had more than tripled. Not sure what the deal is, but all is fine after uninstalling this.

LOVE IT ! Rated 5 out of 5 stars

I'm getting a message in every account that I check: "Sign-in attempt prevented", about once a day. Is there anything I need to do ? I do not use 2-step verification.

What a great replacement for Gmail Manager!

Rated 5 out of 5 stars

Yes, it's very useful to be able to check many Gmail account in parallel. Please make sure it's working with all version of Firefox.
