It works just fine with 7 Gmail accounts. The only feature that is missing is to reset the counter after a specific Gmail account opens and the mail has been read. It has to be done manually by pressing the refresh button.

No more than one gmail account. Others does not work.

Works good, but only if you only have one (1) gmail account. Says it works with multiple gmail accounts - WRONG!

was working then one day it just stopped

It does not work with the version of firefox quantun, the icon does not appear in the taskbar, it does not work with any gmail account, yahoo, hotmail, does not do anything

Very lightweight and responsive. In my case it checks 3 gmail, 1 yahoo and 1 outlook accounts. If for some reason it does not work, it is probably because for some reason the cookies are deleted, maybe from a plugin. The X-notifier should work better for cookie meddlers out there.

Work flawlessly with Outlook.com. I think it is the best email notifier addon in AMO.
Better if it can reset counters after click, like X-notifier does.

no work!

Simply does not work ... too many problems guys ( cookies maybe?!? )

Недостаток 1й) Когда внизу справа появляется табличка о новом письме, то если её кликнуть - письмо выбрасывается В КОРЗИНУ! Это же идиотизм!

Недостаток 2й) Редко проверяет почту. Самое частое - раз в минуту. А я бы хотел каждые 30 секунд.

This has been working pretty well for me, much better than Gmail Notifier.

Unfortunately, it doesnt't working with Gmail

As told in subjet... :(

it simply doesn't work

Thank you for the great extension.

There's one problem regarding it when using it with "Auto Delete Cookies" extension, which auto deletes cookies directly after closing the tab. Because of this, this extension doesn't work after the tab is closed. Because it seems to me that it depends on cookies to do its job. I think a better approach would be storing the passwords locally in an encrypted way?

Thank you.

An option for dark themes will be super, because i have black text in the menues with dark backround, so it will be difficult to decipher the texts... Otherwise its a top AddOn.

Used to work but not any more

It says "this addon could not be installed because it appears to be corrupt".

It's no use.
